What I'm looking for

I'm comfortable with both long-term engagements and short-term assignments, and I work autonomously across the full stack—from architecture and interfaces to APIs, databases, SEO, and accessibility.

At France Travail, I designed and built the front-end architecture for Mes aides France Travail, a public platform surfacing financial and material support for job seekers. SEO work helped the platform reach close to 90k monthly visitors, and I drove accessibility efforts toward the RGAA 4 standard.

I also supported the Travailler en France mobile app, building sign-up forms and story-style explainer screens within an existing codebase. I’ve worked across front end, back end, APIs, and databases, with experience in React, Next.js, Vue.js, Node.js, and TypeScript.

On personal projects, I built Trip Meter, a GPS-based PWA for following rally road-books, and maintain Cube Gallery, an open-source JavaScript package. I also maintain The Petrolhead, an automotive photography gallery that I’ve rebuilt over time with Next.js, SQLite, and Drizzle ORM.
