Ex-Google engineer, 10+ years in software, last 2+ focused fully on GenAI. I’m looking for consulting and hands-on work, not just giving advice.
I help teams integrate LLMs into real-world workflows. Comfortable working across the stack (Python, React), from quick prototypes to production systems.
Past work includes agentic workflows, eval pipelines, prompt frameworks, GPT-powered tools, and full-stack AI products.
I prefer working directly with stakeholders. Big fan of startups.

About Me:
I'm a full-stack developer with a focus on building entire products, not just features. Since 2018, I've been helping startups and founders turn ideas into reality. I'm comfortable owning the whole stack, from provisioning AWS resources to polishing the front-end.
One of my recent projects involved building a USMCA compliance tool from scratch. I took a manual, spreadsheet-heavy process and turned it into a web app that provides a go/no-go qualification in under a minute. The stack was Python on AWS Lambda, DynamoDB, and React.
I also enjoy working with a lighter-weight stack and recently built my own SaaS product (a time-tracker for freelancers) using Django, HTMX, and AlpineJS.
I'm looking for clients who need a reliable, senior-level engineer to build robust solutions to complex business problems.
Send me an email with your needs and I'll reply to schedule a quick 15 min call.
I am a Site Reliability Engineer (SRE), Google Style, with experience at both large and small organizations. I can help you build a Platform Engineering practice from the very beginning. I'm looking to help small dev teams increase their velocity by implementing best-practices of Devops: CI/CD, Kubernetes Deployments, and effective Monitoring frameworks.

8+ years of professional experience. 12+ years of coding if counting my passion since childhood.
I have built and launched Weezem on 2021, and maintained it since. 100k registered users.
I have built and launched SPART on 2021 too, and maintained it until 2024. (for a client)
I have fun projects such as an OpenGL engine or completed the Turing Complete game (learn about CPU design).
I am an excellent communicator and listener, self-directed, and fast learner.
I left my previous job after 5 years with the same people. I am now looking for my next chapter.
I'm a fractional CTO and hands-on product engineer with over 17 years of startup experience. I help non-technical founders turn ideas into reality - working products and teams that provide a solid foundation for profitability, fundraising, and growth.
I offer the following services:
1. Product design - design a product that users want, investors back, and engineers can actually build.
2. Product development - build a quality product quickly and start gathering feedback from customers and potential investors as early as possible.
3. Engineering management - hire, onboard, and lead a lean engineering team to accelerate product development and optimize cost.
4. Technical consulting - pick a tech stack and processes appropriate for the current stage without putting future growth at risk.
5. Project rescues - get your project back on track, understand why it went off the rails, and ensure it'll stay on the right track.
If that sounds like what you need then let's chat: contact@gregnavis.com
I've worked across many stacks, but prefer tried and true tech: React + TypeScript or Hotwire on the frontend; Ruby on Rails on the backend. I also have significant experience with Elixir (+ Phoenix) and Python (+ Flask).

Hey, I'm Tim, a senior fullstack developer from New York, now based in Mexico. I have more than 12 YoE on all kinds of web apps as well as mobile and server environments. I love backend and APIs, but I have a passion for pixel-perfect UIs and frontend magic. I have built many of my own projects from start to finish so I have learned a lot about good UX/UI, can choose the best technologies for the job, spot problems before they arrive and write solid tests. My prior career in journalism made me a great communicator and writer. I also enjoy devops and managing servers using Linux, Docker and Kubernetes. I have built many apps on AWS and Google Cloud, including using Terraform for infra and Github Actions for CI/CD.
Right now, I have a side hustle bootstrapping Hot Page (https://hot.page) and releasing native HTML web components as part of my open source project HotFX (https://fx.hot.page).
Senior Role:
C# and Python: If you have XAF experience (and preferably already have a DevExpress license?) AND some LLM API (Semantic Kernel or direct) experience, talk to me about some mainstream LOB work. WinForms and Blazor, document processing/OCR workflow, light deployment/devops tasks, integrating Python and C# based workflows.
---
Junior Role:
Front-end JS (including ThreeJS/Babylon) and light Python backend work, LLM API's. Set up cloud services, create/maintain a web/social media presence, some marketing/'growth hacking' tasks, writing docs/consumer text. Probably a good fit for someone who's working on their own micro-SaaS.

Please include an hourly/weekly rate, and a one-sentence mention of what your current/preferred AI coding tool workflow is. sep2025-contractor@waldrews.anonaddy.com
In past 20 years did many different projects, mostly worked with teams 1-5. 60% of projects were related to sport and TV, for example recording and archiving thousands of videos, creating encoding and playback pipeline, rest was various other fields. I was jumping between leading, architecting, designing, programming and things in-between :)
I have most experience mwith C# (web services, aspnet, razor, ...) also desktop apps (WinForms, WPF, Avalonia), JS/Typescript (mostly for gui, I enjoyed mithril and now SolidJS). I also did some c++ for various small integrations (for example some plugin for Godot, some ffmpeg. Last year I focused heavily on Rust, and created user space network bonding protocol. I mostly worked with GPC 70% , AWS 20%, other (like Hetzner) 10%.
I like to make GUI/backends that makes sense, are easy to understand (test with users) and performant/fast. Also to last years, with minimum dependencies. I also have experience with live events setup for broadcast of events, have experience with networks.
I did tons of remote support with people around the world, also know how to use this information to make better programs (or design...). Looking for 20-100 hours per month.
Last year I started solo career and am now slowly building better references :)

Like this Ask HN: Recommend employers with positive social impact [https://news.ycombinator.com/item?id=31518945], I am looking for similar work, but I am open to work on any interesting project. I am a European software developer who has lived and worked on four continents. Now it's time to move on and so I am in the process to relocate to Africa.
I have more than a decade of experience running a company, doing software development, support and training and mentoring adults and students, as well as working on educational projects, and I am willing to take on a mixture of roles as needed to support a project.
I value good teamwork over fancy tech, and I don't shy away from working on legacy code. I am primarily motivated by solving problems, so let me help you solve your problems.
I am open to work for companies anywhere as long as the work can be done fully remote from Africa.
While I could find a job elsewhere I believe that the experience living in an area where my work is going to have an impact gives me a better understanding of the needs of the location I am serving. Whether it is through direct contact with clients and users or just by being part of a local community and learning about the reality of living there.
In addition, I want to use some of my income to hire local interns and junior developers and train them in order to pass on my experience. I also sponsor children that otherwise can't afford to go to school (see my website). If you want to support this, I would love to work with you. Also if you are interested in hiring African developers yourself. I can help you build up your team.
I have a decade of experience founding and advising startups; a decade of experience as a software developer and tech lead; and a wide variety of supporting experiences. Let me help your business get to the next stage of success.

I'm a solo consultant with some availability at the moment and looking to fill the time. Former startup CTO and full-stack developer, I've been doing systems programming for the last 18 months. Recently I've been working on a cryptography/security project for a scam prevention product with OpenSSL and FFI in Zig.
I'd love to do more systems work in Zig (or similar languages). I also have extensive experience with Laravel, React, and TypeScript, can conduct performance and security audits, and help with AI processes, training, and best practices. Looking for mostly short contracts but open to ad-hoc work or other interesting offers.
Recent project: audited a new Laravel application for a local company that was mostly vibe coded - reviewed for security, performance, tech debt, testing, and general architecture. Also completed cryptographic protocol implementation for fraud prevention and various Zig ecosystem contributions.

I'm a backend developer who has worked extensively with Golang for 5.5 years and designed/built/updated numerous complex APIs and services, some from scratch. Over time, through production experiences and a few mentors, I've learnt to write code that's cleaner, more easily extendable, and scalable.
MY IDIOSYNCRASIES: a) I enjoy creating, building and carefully improving things - that's how I got interested in software development 7 years ago (and got a Master's degree in it after having being a teacher for some years). I think, even if I say so myself, that this translates into features that are reliable and robust because I love the process. b) I tend to over-communicate as opposed to under-communicate. c) I love Golang!
AVAILABILITY: 20-23 hours (in any needed timezone) in a week.
TECH STACK (worked a lot with these): Golang, PostgreSQL, Redis, GCP, Docker, Kubernetes
Also worked with these in the past: Python, C#/.NET, AI integration, RAG, Vector databases, Airflow, MongoDB, Kafka, ElasticSearch, AWS, IPFS

I am a Lead Infrastructure Engineer with 20+ years of experience.
Whether your team is stuck troubleshooting infra issues, needs extra hands on an infra-heavy project or is just lacking tech leadership on the DevOps topics, contact me and we'll figure it out.
I prefer to work along the existing engineering teams, mentoring or training them while working together on the real tasks. This is a very effective and also a flexible way to learn and as a bonus, some work gets done on the way.
I am located in EU (Estonia) and work remotely with occasional on-site visits.
The usual topics are various AWS services, Elastic Stack, Linux, wide range of troubleshooting, infrastructure as code, logging & monitoring, managing cloud costs, but I find it rewarding to venture into new areas together with the team.

I'm a full-stack developer with 7+ years of experience in startups trenches.
Here are the biggest projects I've worked on + a single feature that demonstrates my impact on product and/or technical chops :
Fanfest – fanfest.vip - Community engagement platform for soccer fans. Built a browser-based live streaming engine that lets streamers broadcast directly from their browsers in both 16:9 and 9:16 at 1080p (and lower resolutions), with simultaneous streaming to YouTube, Twitch, Facebook, Instagram, and X.com.
Pequity – pequity.com - Compensation management platform for mid-to-large organizations. Built V2 for offer approval chains, reducing complexity and fixing HUGE performance issues. For example, in the worst case scenarion in V1 for a single request it would take 2 minutes to finish. In V2 it's 970ms.
Haekka – haekka.com - Security and compliance training integrated with workplace tools. Developed a system for automatically assigning users training based on non-compliant events like exporting sensitive keys they did in AWS/Slack/Gmail.
Flox – flox.app - App facilitating social connections by helping friend groups meet. Used Postgis to build an algorithm for auto check-in system for event attendance.
I love solving complex problems and have 14 years of experience in Fin-Tech, Journalism, TV and Media, Health, Science, and more.
I've taken countless projects from 0 to 1 working with clients like JPMorgan Chase, Santander Bank, Rob Walling, Trello, Peter Diamandis, Syncthing, SimplyCredit and others. I'm experienced in Vue.js, Django, Phoenix framework, Quasar, just to name a few. I pick up new tech easily and like working on complex products.
I can help you with:
- Product Design: I help identify and solve the real problems your users face. Whether you're struggling with low engagement, confusing user flows, or a product that doesn't quite meet market needs, I dig deep into user pain points to design solutions that actually work. From ground-up product strategy to fixing specific friction points that are hurting your metrics.
- Front-end Development: I can turn the design into a pixel perfect product. Being able to design and develop allows me to move at speeds otherwise impossible by cutting a lot of the steps otherwise needed.

Willing to relocate: no, but willing to travel/visit. I'm flexible with working hours, I usually work with clients from either Western Europe or the USA.
I do dev/devops/security, usually for startups or scale-ups or other small orgs with limited resources, and I've been doing that for 15+ years. So, if you:
* Have a slow web application that’s often down?
* Want to improve security and don’t know where to start?
* Have a legacy system that needs to be replaced?
* Are considering an acquisition but not sure about the technical side?
I can help with that. For example, in the past I have:
* Massively improved performance and reliability for a data visualization platform.
* Led a large effort to improve security for a cybersecurity SaaS.
* Built a micropayments system for a prominent media startup.
* Rebuilt an aging e-learning platform from scratch for a GDPR compliance SaaS.
* Conducted technical due diligence for acquisitions.

I am a software engineer with over 6 years of experience building web applications.
Since my first website at 10 on GeoCities, I've gone on to work on Minecraft custom servers, MMORPGs, web application used by millions, and led volunteer teams to deliver IT services powering a homeless shelter network every Christmas.
I enjoy being "the glue" to IT projects, working across disciplines to ensure they get delivered on time, meet budget and satisfy users. I specialise in modernising legacy applications using modern technologies and frameworks, and have created greenfield applications from scratch.
I speak PHP, Python, JavaScript / TypeScript, and have worked with frameworks like Next.js and FastAPI. My current obsession is headless CMSes (PayloadCMS gets my vote).

I am a backend expert, having built and maintained mission critical, low latency and highly available systems for several 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 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!
* 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 ~50 node, AWS, Dockerized, Terraform-deployed distributed system to provide realtime, transformed trade data from crypto exchanges to a Kafka pipeline and data lake (fodder for an analytics platform). Met 5000msec SLA across arbitrarily many exchanges and ticker symbols. Blue-green deployment for complete CICD safety. Cloudwatch metrics proved SLA was met and provided general system oversight.
* 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.
