Available for new projects
I help startups, product teams and agencies ship, rebuild and speed up their web applications.
I also build my own products, like Grindrise. I think product, not just code.
Based in Francheville, near Lyon, France. Remote work anywhere in France.
01 · What I offer
From an idea or a mockup to a V1 in production: front end, API, database, auth, payments. On a codebase a team can take over.
Taking over existing code, modernization, migrations, splitting into services, load times. That's what I do at Likewatt: load times cut in half.
White-label technical subcontracting. I work within your conventions and with your tools.
A feature to ship, a code audit, an architecture review. A short engagement with a clear deliverable.
02 · Why work with me
Full-stack developer at Likewatt, a SaaS vendor. Interface redesign, Firebase → MongoDB migration, split into microservices: load times cut in half for more than 2,000 professional users, including teams at TotalEnergies, Crédit Agricole and Eiffage.
A mobile fitness tracker built with React Native and NestJS, with an anti-cheat model enforced by the server. Building my own product makes me think about engagement and retention, not just code.
End-to-end typed code, tests on sensitive logic, CI, code reviews, documentation. Holder of the French Application Designer-Developer degree (RNCP level 6).
React, Next.js, TypeScript, NestJS, React Native, PostgreSQL, MongoDB. I use AI tools like Claude Code to ship faster, with systematic code review.

Generic building blocks I created before the engagement remain mine, and you can use them freely in your project. Development happens in your repo or a dedicated one, and delivery includes documentation and handover to your team.
