Freelancer profile translated to English.

Description

I design and develop custom web and business applications for SMEs and mid-sized companies that need a senior developer capable of working autonomously, from end to end.

My core stack: React on the frontend, Node.js + REST API on the backend, PostgreSQL for data. Online payment integration via Stripe. I deliver robust, maintainable applications focused on real usage — not prototypes.

When a project requires a mobile version, I naturally extend to React Native — a single codebase, coherent web and mobile.

When a project involves mapping or geospatial data, I bring rare expertise: PostGIS, OpenLayers, Leaflet, GeoServer — from spatial storage to interactive maps in the browser.

With 25 years of experience, I have worked on complex projects for GRTgaz, SNCF, IGN, the World Bank, and local authorities. I work on new applications as well as on taking over or evolving existing ones.

Acceleration by generative AI (Claude, Cursor) integrated into my workflow — up to ×5 on observed delivery times. My 25 years of experience allow me to master AI drifts and guarantee solid, maintainable code without hidden technical debt.

Based in Vannes, I work mainly remotely. Response within 1 hour.
