We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.
We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.
Ex-Google engineer, 10+ years in software, last 2+ focused fully on GenAI. I take projects from idea to production.
Recently built an end-to-end evaluation pipeline for a security platform’s GenAI search (RAG), improving retrieval quality and minimizing hallucinations.
Tech: Python · LangChain · RAG/evaluation · Prompt engineering · React
Past work spans agentic workflows, prompt frameworks, GPT-powered tools, and full-stack AI products.
Prefer working directly with stakeholders. Big fan of startups.

I have extensive experience building software with Python and Javascript (along with their respective frameworks and libraries).
I built closedlinks.com which introduces a very simple yet powerful model for secure, anonymous sharing through one-time access links that leave no traceable sender fingerprint. Unlike conventional tools that prioritize persistence and traceability, ClosedLinks is purpose-built for interactions where privacy, control, and non-attribution are essential.
If you want to read more on why I built it and how it works, check out the white paper - https://www.closedlinks.com/white-paper/
Technologies I Use -
- Frontend: HTML, CSS, Vanilla JavaScript, TypeScript, Svelte, React, Material UI, Bootstrap, Three.js
- Backend: Django, Express.js
- Others: Experience integrating third-party APIs like Stripe, Flutterwave, Coda, Circle.so, Dropbox, Google authentication, Brevo, OpenAI etc.
Let me help build for you or join your team!
Hi there. Long time Ruby on Rails developer looking for contract/freelance work. Short or long term is fine. I’ve done Rails at Shopify, Apple, Intuit, and some startups both successful and not.
I'm mostly in San Diego, CA, USA, but work EST hours. I typically work remote, but happy to travel regularly.
A bit more info on my personal site http://bradlyfeeley.com and my email is in my HN profile.
Thanks!

Last September I built an AI inference tool that hit #3 on HN (https://news.ycombinator.com/item?id=41620530). It processed 17.3M messages in 24 hours and only cost $17 to run.
I specialize in:
- LLM inference optimization (FastAPI, proper batching, memory management)
- CI/CD pipelines for ML deployments
- Making AI systems cost-effective at scale
Recent work: FrankenClaude (reasoning injection experiments, https://thelisowe.substack.com/p/frankenclaude-injecting-dee...), self driving Rocket League (https://thelisowe.substack.com/p/building-an-ai-that-plays-r...), diffdev (AI-powered code modification tool, https://pypi.org/project/diffdev/).
Previously at Sprout Social where I built their ML inference platform - reduced deployment time from 6 months to 6 hours and cut AWS costs by $500K/yr.
Looking for interesting problems in AI infrastructure, performance optimization, or building products from scratch.
Tech: PyTorch, FastAPI, K8s, Docker, AWS, ONNX
