I am a senior Full Stack AI Engineer with 8+ years building agentic AI systems, GenAI products, and AI-driven automation, backed by deep full-stack expertise in Python, FastAPI, TypeScript, React, and Next.js. Proven track record architecting multi-agent workflows and LLM-integrated platforms including an AI-powered ads platform that cut campaign launch time 6× and generative learning tools that reduced educator prep time 45%. Seeking to apply agent orchestration, LLM integration, and intelligent automation to accelerate product innovation and measurable business impact.
I built 3 products from idea to paying customers. So I can help your startup with architecture, implementation plans, and writing specs that you need to keep vibecoding sane. Depending on whether I get into YC (or most likely not, applied with just an idea), I might have free time coming up in the upcoming months.

I’m Mark, a Dutch product designer working from strategy to shipped code. Always have, it’s what got me hooked on design over a decade ago. Since, I’ve worn many hats working in startups and for myself.
I love collaborating with founders and small teams. By working across design, engineering, and product, I help them build simple, effective, and reliable software.
I’m ideally looking for a company where I get to go beyond making pictures of interfaces. A place where I get to work end-to-end from ideas to visuals to the finished product.

I’m a senior generalist engineer with founding-style ownership. I like building systems end-to-end: protocol and product code, backend platforms, infrastructure, internal tools, and product-facing surfaces. Several times I was either an initial or an early hire in small and large-scale projects and products.
For the last two years, I was a founding engineer at Load Network, an early-stage L1 EVM chain with Arweave-based data settlement. I worked across the stack: developed protocol-level abstractions, consensus and execution clients, bootstrapped infrastructure, DevOps, and smart-contract prototypes. I also built private AI agent harnesses, ran multi-agent tests, and used LLMs for spec review and cross-client protocol design research and data gathering.
Before that, I spent six years in gamedev building backend platforms for massive-scale games at Strikerz/UFL (uflgame.com) and Vizor Games. I was an early hire, working directly with the CTO to build the infrastructure and design the system from the ground up. I engineered microservices for matchmaking, game economy/payments, quests, auth, moderation, and data pipelines (Kafka, Postgres, ClickHouse). I also managed Kubernetes, observability, internal admin tooling in Python/JS, and took part in high-stakes production launches.
I built my engineering foundation in enterprise Business Intelligence and Data Architecture. I shipped large-scale data warehouses (OLAP) for global companies (pharma, logistics), writing heavily optimized Oracle PL/SQL and T-SQL.
Open source: Merged contributions to the Ethereum ecosystem, including the Reth client in Rust, Flashbots SUAVE, and Alloy.
These days, I'm spending more time on product-facing surfaces (React, Rails), exploring Zig, and using LLMs for the right dose of entropy and speed.
Looking for: founding engineer, senior/staff software engineer, full-stack or backend roles where broad ownership and technical depth matter.

I took a break from freelancing for a while to run a crazy experiment. 25 projects in 25 weeks. A lot of it was experimental: https://stevenirby.me
It was a lot of fun. I was featured in TechCrunch, Engadget, and many more. I was on the front page of HN 4 times.
So now I'm looking for a freelance position where I can help a team with product development or AI stuff.

For YC founders (or equivalent serious startups).
Ex-Silicon Valley engineer at junior-engineer cost. FAANG, YC, and OCV startup experience. Senior engineer by choice — IC track, no management ladder, working remote from the EU.
First task free, no invoice. Pick something off your backlog. I ship it. You decide.
No commitment after that. Contract, monthly invoice. Cancel anytime.
Free brainstorm calls — even if you never hire me. 30 min, no pitch.
EU timezone, 4 hours daily Bay Area overlap.
I am a backend expert, having built and maintained mission critical, low latency and highly available systems for many companies over the last 10 years, in addition to over 20 total years of software development experience. I learn new things extremely quickly. AWS preferred but not required (I hold a variety of certs, available here: https://www.credly.com/users/jon-north.ad78f0c8)
You will like working with me because I:
* hold your goals as my priorities
* communicate verbosely yet synthesize well
* my rates are reasonable in exchange for the value I deliver
* I guarantee I will get the job done
* built the primary streaming data architecture for realtime game player tracking information (all games, 50ms SLA) and game stats for one of the top 3 US sports leagues (can’t name drop!) using Redpanda/Kafka on Azure+Terraform, and implemented its developer portal using Gravitee to provide first class streaming API support and monetization. Also built, deployed and maintained their ask-a-question-get-a-true-answer AI bot to expose 20+ years of stats to natural language fan questions! (this was the third of currently four times I’ve built similar architectures for different companies)
* Implemented a vector DB for one of the leading AI image hallucination platforms (millions of users) to provide an image similarity service.
* replatformed dozens of complex quant jobs to AWS Lambda for a startup hedge fund (~$1B AUM), vastly improving QoS and maintenance cost. Line 1 to platform-in-prod time 3 months, including refactoring for fit. This was mission critical cannot-fail stuff and required extensive proof of correctness.
* built a framework to collapse dozens of singleton ETL programs into one config-driven, simple C# application performing the same functionality at ~80% reduction in maintenance cost year over year.

Hi! I work for clients in the US and Europe on projects across energy, edtech and finance. My most recent work has been heavily AI oriented, so I now call myself an AI Engineer, but I'm also a full stack web developer and throw up infra with terraform in GCP or AWS.
I'm familiar with a bunch of technologies, including but not limited to TypeScript, python, Unity3D, WebGL, .Net core, and others. I've been in this industry for 20+ years now and what I've seen work is the same now as it was then: solid communication, simple architecture, pragmatism, and velocity.
My rate is $110/hour and you can reach me at davedx@gmail.com - let's get shippin'!

We've built a new platform in the electronic music space, currently in limited beta, and we are seeking freelancers who love electronic music to help us with design, UI/UX, and infrastructure (major bonus points if you're an artist or promoter, or you travel extensively with music as a primary focus).
1) We want to scale our infrastructure up to 500 RPS while minimizing costs when it isn't in a burst period, validate that with load-testing, and set up monitoring, alerts, and auto-recovery mechanisms where possible.
2) We'd like a complete design and UI/UX refresh. This can be an individual who holds both sets of skills or two distinct people.
Please email ${this_username}@gmail.com if this sounds like a fit; every application will receive a response.
I'm currently working on a "better Terraform" called unobin. https://github.com/cloudboss/unobin

Senior Systems Architect and Technical Lead with 20+ years of experience. Current role involves managing teams and high-level architecture for international clients. While enjoyable, it leaves less time to write code or set up servers—the hands-on work I've always loved. Looking for freelance projects (~5 hours/day + weekends) to stay sharp and build interesting things.
Availability: Highly flexible. Easily adjust my schedule to align with US or Asia timezones for meetings and syncs as needed.
Backend & Data: Python, PHP, advanced SQL (MySQL/MariaDB), HTTP/REST APIs, complex web scraping architectures. Infra & Virtualization: Linux (Ubuntu/RHEL) kernel tuning, KVM, OpenVZ, high-availability clusters, AWS/GCP/Hetzner, Docker. Networking & Security: Nginx (caching & load balancing), Cloudflare, OpenVPN, BIND server administration, strict DNS security (DMARC/DKIM/SPF), firewall tuning.
Work Ethic: Detail-focused with zero tolerance for unhandled bugs and noisy error logs. Fast communication, proactive updates, and strict adherence to deadlines are standard.
Due to strict NDAs with current company/clients, public profiles are kept scrubbed. More than happy to complete a small paid test task or a time-boxed pilot project to demonstrate code quality and architectural thinking.
Treating your business as my own means delivering more than just ticket execution.
Focus is always on Cost Optimization: Identifying and eliminating cloud infrastructure waste. Revenue Growth: Structuring robust technical architectures that directly support business scaling. Proactive Prototyping: Suggesting and building architectural improvements instead of just waiting for instructions.
