What I'm looking for

I'm looking to build and lead production-ready products remotely, taking complex fullstack and mobile systems from idea to launch for clients in the US and Europe.

I've built and led fullstack products for fast-growing startups, from Cajoo's quick-commerce operations to EuroSX's tokenised asset exchange under banking-grade constraints.

At Mode Agency, I'm the sole developer behind a photography platform spanning a Next.js public site and admin panel, Supabase, media-processing workers, an iOS app, CI/CD, monitoring, and document-extraction workflows.

Through Kompa, I founded and built Ratio, an iOS training app, and Mustyn, a call sheet SaaS for US film and commercial production. Both products include natural-language experiences that let users drive workflows conversationally.

I work remotely from France in English with US and European clients, and can lead a team or take a product from scratch to production independently.
