Е-mаil: hn-september at kol3x dot com

I started as a fullstack JS engineer and grew into product development at my last company. I owned the ingestion layer - collecting 100k relevant messages/month from 4 platforms through a dirt-cheap serverless back-end on Cloudflare Workers.

We worked with LLMs deeply, especially in code generation research. I was part of a small team developing SpecGEM, a fine-tuned model that generates Cloudflare Workers code from JSDoc comments and is designed to outperform mainstream LLMs at this narrow task. https://dn.institute/research/ai/specgem/

Last month I released a self-hosted LLM assistant on Cloudflare Workers that predictably compounds context across conversations. https://github.com/kol3x/pawmc

Looking for a remote role where I can own work end-to-end. Stack-wise I'm strongest on Cloudflare Workers, JavaScript/TypeScript, practical LLM integration, React.

Résumé/CV: https://thaler.dev/thaler.cv.pdf

Email: dmitry@thaler.dev

Full-stack engineer with a backend focus and 15+ years of experience. Most of my work is at the integration layer: pulling a dozen awkward external systems into one GraphQL or REST API that a product team can rely on. This has included payment gateways and government services at a national lottery, multi-protocol network telemetry, and billions of retail sales and inventory rows.

I own the infrastructure under what I build. On one route-planning system, that meant dynamic scaling that spun up short-lived machines at peak while keeping the cloud bill flat.

EU-based B2B contractor; no sponsorship required. Experienced working remotely with US companies via Deel and Globalization Partners. Available with 7 days’ notice.

Software architect, 15+ years in production systems, almost entirely startups and internal startups — fintech, e-commerce, pharma, publishing.

The work I get pulled into is the recurring startup problem: a service shipped fast under launch pressure, without adequate tests, that later has to be made reliable without being stopped. Incident response, re-architecture, and the release discipline that keeps it from happening again. Most recently that has meant a regulated UK consumer-credit platform — loan servicing, arrears, forbearance, statutory breathing space, and early-settlement calculations written against consumer-credit legislation. Regulation as code, behind a test suite larger than the production codebase.

I've done that in all three configurations: taking a core system from problem statement to release, leading the team that carried it (1 to 7 engineers in ten months), and now doing the same work again with agentic tooling covering what the team used to.

On the data side: a LightGBM acquisition model over a 38M-row base — 0.77 test AUC, 8x lift in the top 1% — scoring 2.9M households for a live campaign. I also found a validation-set misuse defect in my own pipeline (early stopping on the test split), quantified its effect across every published figure, and added a pure-noise regression test to pin the corrected result to chance. NLP is hands-on rather than API-deep: my degree thesis fine-tuned BERT, RoBERTa and XLNet to state of the art on the FNC-1 stance-detection benchmark, published at LREC 2020.

Building on my own time: github.com/vslovik/fenix — a local market-signal scanner (Ollama embeddings, sqlite-vec, no API keys) that ranks incoming articles against a free-text description of what you're looking for, and answers questions over the same corpus with citations back to the source chunks. Also a tool-calling agent that turns unstructured regulatory text into a deterministic calculation pipeline, where the model does the extraction and a deterministic engine does the arithmetic.

Looking for agentic AI/LLM engineering, LLM evaluation and observability, AI integration, or software architecture. Founding-engineer shape suits me — early enough that I'm in the room where the work gets defined. Employment or named-delivery consulting, not disguised staffing.

Remote: Yes — remote only (~EU hours or async)

Willing to relocate: No

Technologies: Python, PostgreSQL, FastAPI; LLMs & embeddings, semantic search, self-hosted open-weights models (on-prem, offline); deterministic data/ML pipelines; PDF/document extraction, OCR, IoT, time-series, logs → decision-useful information

Trustworthy output from untrustworthy data. I build systems that catch what's silently wrong — a dead sensor nobody noticed, contradictory records, a garbled scan, a confidently-wrong model — so it surfaces as a flag today, not a six-month catastrophe.

I use LLMs where they earn their place (development, meaning, embeddings, plain-language access to jargon-locked data) and keep them out of decisions and the data flow, which stay deterministic and verifiable. An LLM can help you find the answer; it can't be the answer.

Senior systems engineer, multiple AI cycles of judgment on what survives the hype and where it breaks. Currently turning messy Polish legal PDFs into a correctness-checked graph — the hard part is the verification, not the AI. Previously I built a legislative-notification service that ran autonomously in production for over three years before I retired it. I've written about where AI coding agents actually fail and why verification is the real work: https://walat.eu

Best fit when: correctness matters, the data is real-world-messy, and you want someone who names what doesn't work and why.

Full-stack web developer with 20 years of experience, currently working at a startup where I was employee #2.

My strongest area of expertise, if I had to point one out, is frontend. I've built complex multiscreen dashboards, mobile games, IPTV set-top box interfaces, you name it. Consistent and performant UIs are my jam.

I enjoy working with people, I've happily and successfully led teams, conducted dozens of technical interviews and managed cross-team initiatives. That said, I'm a deeply technical person at heart, so I'm not looking for a full-time management position.

Over the past year I've been working with LLMs extensively, building an AI asset management product at my current employer, which required diving into coding harness internals and shipping features supported by LLMs. Our development processes started relying on LLMs as well, so I'm well prepared to join a team that's already heavy on AI or help it make that transition.

My preferred environment is one where I get a seat at the table early so I can own a feature from conception to production. I'm used to low overhead, frequent exchanges with product people and daily deploys. If you're not there yet, I can help you get there.

Résumé/CV: https://notes.pixeletes.com/cv/

Email: pixeletes@proton.me

I'm Victor, a product designer who writes production code, fifteen years in. I can carry the backend and I have led teams, but I engage most with the user-facing parts. I'm most useful where design and build are the same job: 0-to-1 products.

Recent side work: LLM Party (https://llmparty.pixeletes.com), a set of LLM experiments, and SketchJam, a multiplayer creative-coding party game.

Notes on how I work: https://notes.pixeletes.com

Head of People / People and Talent leader with 15+ years of experience across startups and larger technology companies. I have served as the first/only People leader at venture backed startups, partnering directly with founders and executive teams across hiring, organizational design, performance, compensation, People Ops, employee relations and scaling through significant change.

I particularly enjoy the 0→1 and growth stage work, figuring out what the business needs, building the right People foundations without unnecessary bureaucracy and staying hands on enough to actually get things done.

Most recently, I founded and built an AI powered consumer startup, which has given me firsthand experience on the other side of the founder/People partnership. I am continuing to build it in my own time while looking for my next Head of People opportunity.

Open to full-time Head of People / VP People roles as well as select fractional opportunities.

Embedded HMI engineer. For 5 years I was the sole software owner of ~12 operator dashboards that shipped to production on heavy agricultural machinery for five OEMs: architecture, C firmware, J1939 modeling at 250 kbps, the entire graphics layer, bench and field validation, and support. Two things I'm proud of: integrating an electronic Cummins engine and a DANA transmission so the machine was commanded from our own HMI/VCU with no OEM display, and replacing European OEM valve controllers with an in-house CAN + HMI module, which cut per-unit cost and license fees.

I also built VisionUI, my own desktop UI framework: custom 2D engine, WYSIWYG editor, licensing and cloud backend, with performance-critical parts in Rust.

Looking for embedded or industrial HMI, Qt/QML, machine and instrumentation software, or graphics-heavy desktop apps. Full-time or contract. I'm used to owning a product end to end.

Software engineer, 2 years, remote for UK companies. I build the layer that makes AI features safe to ship.

Spotter — https://github.com/anasbayoumy/spotter Evaluation and guardrail layer for LLM agents. Deterministic rules run before any model judge, because a rule can't hallucinate a pass. Every call traced before it executes, so when quality drops you query what changed.

CLOCKLO — https://clocklo.com Multi-tenant workforce SaaS. AI attendance verification, RBAC, Stripe, CI/CD on AWS. Shipped solo, end to end.

SofClinic — https://sofclinic.com Clinic management SaaS, WhatsApp-native — clinics already run on WhatsApp, not another dashboard.

Also built an agents module where the LLM emitted SQL and got back only record IDs, never customer data.

Open to full-time or contract, 4h/day and up.

What I am good for: quick turnarounds on existing apps (crashes, Gradle and build errors, Play Store rejections - usually 24-48h), full Flutter apps shipped to both stores, and website-to-app conversions.

Code you can read before hiring me: I published an open-source photo and video editing SDK for Android on GitHub (https://github.com/Raxit0948), and I just built a free interactive Play Store pre-submission checklist - https://raxit0948.github.io/playstore-preflight.html - 14 real rejection causes with the fix under each one. Happy to start with a small paid task so we can both see how the other works.

Remote: Yes (preferred)

Willing to relocate: For the right role, though I prefer to remain in the PNW

Seeking: Platform / Infrastructure / SRE / DevOps; also HPC, research infrastructure, and scientific computing roles

Technologies:

    * Infrastructure: Linux (Rocky/Debian/Arch), Kubernetes, Docker, Ansible, NGINX, GitHub Actions / CI/CD
    * Systems and networking: DNS (BIND/TinyDNS), Kea DHCP, NetBox, Zabbix, Harvester, Ceph

I'm a PhD physicist turned infrastructure engineer. I maintain a 40+ node Linux fleet for an open-source blockchain project; covering automation, monitoring, deployments, and public services. I also run a small web-hosting business and have built cloud automation for bare-metal onboarding and Kubernetes-hosted VMs at a startup.

My earlier work was in computational biophysics, ML, and HPC.

I'm looking for a hands-on platform, infrastructure, SRE, or DevOps role, ideally on a small, collaborative team. I'm also interested in research or ML infrastructure roles where my scientific background would be useful. Having worked at startups in the past, I'm fine wearing multiple hats and enjoy the variety.

Systems plumbing, concurrent pipelines, and secure runtime isolation for agent startups. The claim I'd rather be judged on: not that my agents are correct, but that being wrong is discoverable. Write-up: https://sriramvarun0636.github.io/

Vasool — compliance-gated payment recovery agent on Razorpay's test APIs. I pre-registered seven falsification criteria before running anything, and then lost against one: a dumb baseline that retries everything recovers 16.35pp more than mine. It also breaks policy in 1,000 of 1,000 seeded runs; mine breaks it in 0. That trade is the finding, and it's the second section of the README, not an appendix. The LLM never calls a tool — inert verdict type, no adapter to the execution plane, asserted by an import-graph test. Simulated outcomes, tagged as such in the source; every figure is a key in a committed manifest, so you can check any number without running anything. https://github.com/sriramvarun0636/Vasool — 5-min walkthrough: https://youtube.com/watch?v=B0Iov6qAaqs

AutoPatch-AI — autonomous code remediation agent on a LangGraph state machine. Zero-trust Docker execution layer (network_disabled, 256MB RAM, 128 PID cgroup caps), real-time telemetry over thread-safe queues via SSE, AST-based parsing that cut context bloat ~80%. https://github.com/sriramvarun0636/AutoPatch-AI — 90s sandbox demo: https://www.loom.com/share/104cf5ebcfc144a09f49c62830755408

SentinelPrime — multi-threaded options system on live WebSocket data. Releases the GIL via Numba (nogil=True), actor model over daemon threads isolating DB I/O and API calls, fixed-size ring buffers to kill allocation overhead under 24/7 operation. https://github.com/sriramvarun0636/SentinelPrime

Looking for backend/infra/agent-systems work at pre-seed to Series A — founding engineer or engineer #2-5. Eval and agent-safety teams too. Standard loops are fine, and I'll also take a paid 2-3 week trial sprint on a real bottleneck in your codebase.

Hi, I'm Michael Geary. I've programmed in many languages and environments over the years. Some of my current interests are:

• Developer experience. I love helping my fellow developers solve problems, and building tools to make their jobs easier and more enjoyable.

• Aviation and geographic data. For example, airspace and obstacle data importers for Wing; election results and voter information maps for Google; many interactive maps for other companies.

• Hardware interfacing. In a way, I am a "full stack" developer, but my stack may involve a front end to a piece of hardware rather than the cloud. I first got into programming via ham radio, so RF hardware remains an interest.

• Designing and building APIs. Too often an API is designed by exposing the internals of whatever system provides the API. My philosophy is the opposite: start with the apps. I like to build a series of sample apps before starting on the API. This way I can imagine what API will make those apps and others like them easy to build.

• Talk with users! I don't like to sit in a back room cranking out code. I want to make sure it's the right code for what my users need, and that it's easy to maintain and improve as we learn more about what they want.

• Technical and general interest writing.

Open to full time or contract.

I look forward to talking with you!

Seeking: applied AI, model behavior, evaluation, interpretability, inspectability, research engineering, synthetic data generation, or adjacent roles

I have spent more than 15 years building my own tools when the available ones were insufficient, and being someone sent when there was a problem, either to figure out what was going on or solve it, or both.

This has been as a generalist across analytics and data science for the operational arm of a large public university w/ steadily expanding domain responsibility, informing senior leadership, at times authoring strategy and policy. (I'm not as faculty, although I developed and taught a course for several years, Language of Propaganda, as an adjunct lecturer: adversarial uses of language examined through informal logic, cognitive blind spots, and case studies.) Separate from this, when a self-funding hobby found unexpected product-market fit I grew it to side-business and shipped 10,000+ items.

My academic background is in applied linguistics, NLP, cognitive science, and analytic philosophy. I might have followed a research or academic path, but by the time I completed my master's degree, I had concluded that the paths then available would not give me much room to pursue the questions I actually cared about.

Those interests are language, mind, cognition, and computation, all now converged in modern AI, I have devoted a lot of time bringing in ideas from traditional linguistics and some other areas and turning them into practical tools.

Recent work, including live demos:

- Cartogemma: A REPL-like environment for LLM inference. Explore generation as a branching process, preview output, inject tokens, rewind, ablate or restore heads, trace a chosen token through the layers. Per-head projections, residual contributions, the ordinary logit lens, and full-layer output side by side. The CMD/REPL bar functions once loaded. https://huggingface.co/spaces/anotheruserishere/Cartogemma

- Tokescope: watch a model in real time during inference, flag tokens to monitor & intervene. Catch something surfacing, before output. Once flagged it either logs it, stops the response with a hard gate, or suppresses using a gram-schmidt projection that takes the direction out of the vector. https://huggingface.co/spaces/anotheruserishere/Tokescope

- Bertographer is similar, runs on encoder models, classification task, ie NLI models, Also with ad-hoc steering https://huggingface.co/spaces/anotheruserishere/Bertographer

- An instrumentation and intervention library for examining model internals during inference & using them to decompose behavior and outputs. It's what provides core tooling for the HF spaces listed. It analyzes derived structure, across layers and heads. These traces then use linear-algebraic, statistical, and overlap methods such as SVD, PCA, correlation analysis, and Jaccard similarity, results of which can then be used to steer a model through targeted activation-space interventions.

- Another library builds off of this one in the direction of mechanistic interpretability, for finding SAE-like features without the hassle of training an SAE, providing a range of static and interactive visualizations, scanning & storing model states at some or all steps of inference, among other things.

If any of this maps onto a problem your organization has or a role for which you have not found an easy title I would be glad to talk: jim.jdiv@gmail.com

Senior engineer, 10 years, mostly Rails and React with the last year in Flutter and Node on consumer mobile. I own delivery end to end — client requirements through architecture, release, and iteration — and I mentor the developers around me.

Currently running a multi-tenant consumer mobile platform live in three markets, 90+ business partners and 1,500+ users. Second and third deployments needed no rearchitecture.

Also doing a lot of work on codebases built fast with AI tooling: reading them, finding what's actually broken, and telling the owner what's salvageable. Recent example was a Supabase app where parts of the site weren't gated at all and the permission model let anyone escalate their own access via the API.

Open to full-time or contract.

Want to help out healthcare providers? Clinicians using our software are already saving hours a day and loving their job again. We are building Axo to make the software layer as invisible and ambient as possible, letting clinicians direct 100% of their attention to patients rather than screens.

Our first market is orthotics and prosthetics (O&P), the field designing braces and artificial limbs that restore human mobility and underserved by the tech sector. You’ll join as a founding engineer working directly with myself (former Google SWE) and my co-founder (one of the US's best known O&P clinicians), and small engineering team we want to grow.

You will own massive surfaces end-to-end, making foundational architectural decisions for our entire platform. We've got a massive pipeline ahead and need your help to build it. And we participate in humanitarian missions to expand prosthetic access in critical parts of the world like Ukraine and Sri Lanka.

- The Stack: C#/.NET, gRPC, SolidJS/TypeScript, and PostgreSQL, built with strict domain-driven design and rigorous testing.

- How we work: Flexibility! Love AI-assisted speed coding? Go for it. Prefer to write by hand because your mental model is faster than prompting? Perfect. We only care about delivering safely and quickly.

- Requirements: Senior-level depth with production systems, a strong habit of domain modeling, and a philosophy that defaults to simplicity. Strong UI/UX experience with an obsession for user simplicity is a must.

To apply, email me directly at jlyman@axoventures.co with a short story about a favorite technical challenge you solved end-to-end. Please put "HN" in the subject line! MUST be in Texas.

Hello HN, my name is Dan Saul, I am a full-stack software developer with 10+ years building and shipping real products across SaaS, telecom, and business automation. I like practical work: clean maintainable code, reliable systems, and solving the actual problem in front of me.

How I work: I take ownership, do the boring stuff right (tests, reviews, docs, SDLC), and ship. I participate in Agile (Scrum/Kanban) without the theatre, mentor and enjoy being mentored, and contribute to architecture and standards. I love coding by hand but use agent-driven development pragmatically: agents as junior devs where every output is reviewed and tested, not auto-merged.

What I'm looking for: Full-stack or backend-leaning product teams where I can stay hands-on, help set technical direction, and ship software real users rely on. SaaS, internal tools, telecom/comms, or anything practical. I do my best work on small-to-medium teams that value pragmatism, accountability, and continuous improvement over buzzwords.

Recently picked up model benchmarking and training for fun (and personal profit) – https://0xff.nu/hexbench

I spent a decade in support, slowly automating myself out of every role until the tools I built became more valuable than the tickets I closed (at least to me). Now I write Python, creating internal tooling, LLM integrations and automations.

Current projects: hex (https://0xff.nu/hex), an AI executive assistant that manages my calendar, tasks, and Obsidian vault because my ADHD brain certainly won't, and sixwhyo (https://6yo.dev), a code reviewer powered by a 6-year-old's logic. Now also exploring iOS development to create an app I’ve been dreaming about.

I like simple and robust solutions over overly clever architecture, and am looking for a remote-first engineering role, not a support role with "engineer" in the title.

Relocation: Case-by-case

Hi HN, I'm an engineer and data professional interested in team-building, consulting and architecting data pipelines. At Edmunds.com, I worked on a fairly successful ad-tech product and my team bootstrapped a data pipeline using Spark, Databricks, and microservices built with Java, Python, and Scala.

At ATTN:, I re-built an ETL Kubernetes stack, including data loaders and extractors that handle >10,000 API payload extractions daily. I created SOPs for managing data interoperability with Facebook Marketing, Facebook Graph, Instagram Graph, Google DFP, Salesforce, etc.

More recently, I was the CTO and co-founder of a crypto gaming startup. We raised over $6M and I was in charge of building out a team of over a dozen remote engineers and designers, with a breadth of experience ranging from Citibank, to Goldman Sachs, to Microsoft. I moved on, but retain significant equity and a board seat.

I am also a minority owner of a coffee shop in northern Spain. That I'm a top-tier developer goes without saying. I'm interested in flexing my consulting muscle and can help with best practices, architecture, and hiring.

Would love to connect even if it's just for networking!

I maintain Harnix (https://github.com/anakotai/harnix), an open-source scanner for whether a repo is ready for agent workflows. I dogfood the same idea every day: fetch, filter in code, model judges fit, state gets committed.

Otherwise, I'm a fractional CTO: Anakot.AI (compliance automation in Southeast Asia), Aksarapak/Dalo (AI learning, web + iOS), EdTech Connect (CTO through a $2M valuation). Used to write for SitePoint (Docker, DevOps, data). English, Spanish, Portuguese.

Looking for a team that wants agents in the product, with a paper trail. Available now. I overlap EU afternoons and US mornings.

I do not trust what I have not verified, including my own code.

Full-stack dev, 5+ years, last year building LLM products rather than demos. Everything below is something I found by auditing my own work, not by reading about it.

intent-gate — https://www.npmjs.com/package/intent-gate A job posting with hidden instructions got my CV pipeline to write ten years of Kubernetes into my resume. Technology I have never touched. The system prompt told it to use only what was in my facts file and it obeyed the posting instead. What stopped it was a deterministic validator comparing every named technology against ground truth, no model in the loop. A prompt is a request. A check is a guarantee. I published the routing pattern as a library.

job-hunter — https://github.com/ale-aguirre/claude-job-hunter Autonomous job search agent running on my own search. It taught me that my own verifier was lying to me. It counted a URL redirect as a successful application. Aggregate confirmation sat at 78 percent and looked healthy, until I graded per channel and found four integrations at 100 percent and one at zero out of sixty, silently dead for months. The average was hiding it. That number was on my CV and I removed it.

DocUnify — production, private Document comparison SaaS running at an Argentine auto parts manufacturer, 72 employees, in a domain audited against IATF 16949 and ISO 9001. Two people there use it for their actual work. The part I would defend under questioning is the semantic reclassification after the LLM call, because the model kept flagging paraphrases as real differences and embeddings catch that.

This week — https://github.com/theam/facility/pull/242 Merged a fix into an open source AI SDLC project and filed two issues, one about an agent being able to write the field that marks its own check as platform verified. I reproduced the bug on my own machine first and my first repro was a false negative, because bash was eating the backslashes in my test payload.

I'm looking for a flexible role with a healthy work-life balance and a strong, collaborative engineering culture. I value teams that care about balancing quality with speed, thoughtful technical decision-making, and continuous improvement.

Remote: Yes (hybrid ok)

Willing to relocate: No

Technologies: TouchDesigner, Cables.gl, WebGL/GLSL, Figma Plugin API, TypeScript, React, Node.js, Bun, MCP servers, Claude Code, OpenChamber, opencode, Codex

Creative technologist. Two sides: AI tooling and automation for teams, and generative/immersive art. Same instinct either way - prototype fast, make the abstract real.

Recent work:

- Forward-deployed engineer at a large hospitality/marketplace company. Built automation that removed [X hours/week] of manual work.

- Slides and websites generated straight from existing Figma components. Design system in, finished artifact out. Saved a lot of copy-paste

- Currently writing a custom MCP server for a calisthenics training app, so workouts and progress are coached and queried by an agent rather than through the UI.

Looking for full-time or contract work where AI tooling meets creative tech. Teams building something new rather than iterating on what's there.

AI engineer, agentic systems builder and former biomedical researcher. I have 5+ years of development experience and 4+ years building AI systems professionally across startups and larger corporate clients, with work spanning biomedical/clinical AI, finance, content systems, automation and general-purpose LLM applications (including regulation- and compliance-heavy domain work). The common thread is probably best described as “grounded mad scientist” energy. I like getting dropped into problems where there is no roadmap, the inputs are horrible, the requirements are fuzzy and the straightforward-looking solution stops being straightforward approximately fifteen minutes after you touch the real data. I tend to do my best work somewhere around that point.

A few examples:

For a long-term startup client, I effectively became the technical founding person with no repo, no technical guidance and no roadmap in sight. Among other things, I built their AI-driven content and automation ecosystem from scratch. When generic AI output became the problem, I came up with an in-place DPO approach that mined their actual messy Notion editing history, including highlights, strikethroughs and collaborative edits, to generate positive/negative preference pairs for few-shot prompting. No labellers and no fine-tuning. A/B testing, which I also designed for non-technical founders, showed more than 30% improvement in output quality.

For Danaher Corporation via NILG.ai, I built a pharmaceutical pipeline extracting clinical endpoints from FDA drug labels and ClinicalTrials.gov records, then classifying them into higher-level outcome categories. The extraction itself was the easy bit. The interesting work started when the FDA API confidently returned the wrong drug label, source datasets had gaps and seemingly simple client terminology turned out to be inconsistent enough to silently poison downstream analysis. A lot of my work is exactly this: translating fuzzy human requirements into technical systems that are not merely impressive-looking, but actually trustworthy.

For Berkshire Partners, I built a private long-context retrieval and summarisation system over confidential 120-page interview transcripts using locally-run open-source models. This was early 2024, under severe context-window constraints, so I adapted LangChain's refine chain across multiple retrieval rounds to preserve information while generating higher-order outputs such as market forecasts and investment opportunities. Roadmap? Nowhere to be seen.

I also recently had a feature PR merged into Backblaze's open-source genblaze SDK. The docs told users in several places to hash fetched assets themselves for provenance verification, but no shipped tool actually did it. I added opt-in byte-level verification through the existing SSRF-hardened transfer path with DNS pinning, presigned URL credential redaction and per-asset failure isolation. What I enjoyed most was dropping into an unfamiliar codebase, figuring out why earlier architectural decisions had been made and building around those constraints instead of bulldozing through them.

I started my AI engineering career at an AI + NLP research startup called Sagewrite (before the ChatGPT hype took off), where I built substantial chunks of their production backend. I worked on scientific PDF parsing and text-processing pipelines, prepared model-training datasets and built scientific text-generation systems using models including GPT-2. So yes, I’ve been trying to get useful things out of AI slop since GPT-2, which had approximately the literacy of a toddler–work in this field is not a fad pivot for me!

As an erstwhile scientist, I also come with extensive biomedical research experience. My wet-lab background is in immunology, immunotherapy and cancer biology, including doctoral work at Amsterdam UMC and MSc research at CIC BioGUNE that contributed to a Nature Communications paper on Siglec-15. Since moving into AI, I have worked on pharmaceutical and clinical-trial pipelines, PubMed/citation analysis, therapeutic chatbot systems, RAG over biomedical literature and antiviral drug-discovery ML. I am very interested in biomedical/healthtech AI, but absolutely not limited to it.

Outside client work, I am currently building Whitespace, a React/Next.js app that maps a user's professional expertise against the patent landscape to surface unmet needs and generate validated R&D ideas. It uses agentic graphRAG, multi-agent workflows, an adversarial multi-LLM council and human-in-the-loop review. The backend is being built as a proper production system rather than a demo held together with hope: Terraform-defined AWS infrastructure, LangGraph workflows, async orchestration, observability and a lot of thought around security. Demo videos/screencaps linked above.

The other useful thing to know about me is that I learn obscenely fast. My brain usually has about 2048 tabs open, most involving some Google rabbit hole, documentation page or StackOverflow thread explaining why the thing that "should obviously work" does not. I use AI heavily in my coding workflow too, but I am perfectly happy arguing with it until I understand why a design is sound rather than accepting whatever compiles.

Logistics:

I work through Confluente Ltda, my registered Brazilian PJ entity. For overseas companies this can be structured as a straightforward B2B vendor relationship rather than foreign payroll or visa sponsorship. Day to day, I show up, do the work and remain accountable like any other member of the team. Administratively, there is much less cross-border employment machinery for you to deal with.

I have worked remotely with clients across multiple continents and time zones for years, including long-running engagements, so async work and deliberate communication are very normal for me.

Open to full-time, part-time or long-term contract arrangements. Special place in my heart for founding eng roles. Interested in AI/ML engineering, agentic systems, AI-native software development, automation, applied AI and biomedical/healthtech/scientific AI.

English is my first language (I'm an anglophone transplant to Brazil).

I'm very passionate about making sure that the users get a great user experience, and that the quality of the products my team ships are top noch.

Areas I've worked in before and still feel passionate about are: Healthcare, Developer Experience / Developer tools, Multimedia, Productivity Software.

I have worked with teams from early startups to FAANG companies, and while I have no preference I'd work best in a role where I can be involved in product and design discussions as well as engineering ones too.

In my free time lately I've been self-hosting in my own homelab via Proxmox, and building passion projects in Elixir.

Please reach out if you think I'd be a great fit for a team you are hiring for!
