Freelance product engineer and tech lead. 20 years building software products, ten of them as a founder. I work across product, design and code.
Recent work: a control platform that runs indoor farms on three continents, control software for a gravity simulator built with CNES (the French space agency), and a canvas-based rich-text editor that stays fast on documents with millions of words. Details at https://jvelo.at
Now I am building a writing agent on top of that editor. Its edits land as proposals over a clean document: you review them one by one, accept, rewrite, or discuss one with the agent, which comes back with a new version. Proposals stay anchored while you keep typing. It runs its own tool-calling loop on Claude or any OpenRouter model, and every run is traced down to tokens and cost.
Available from mid-October for contract work as a hands-on engineer, tech lead or fractional CTO, full-time or part-time.
