About Guillaume

Independent full-stack engineer since 2012, I work on web projects where technical quality is key.

I support projects end-to-end: architecture, development (Laravel / React), APIs, Linux infrastructure, and even performance and SEO challenges.

Code is designed to last: readability, maintainability, security.

I also integrate AI components (Master's in AI – Université Pierre et Marie Curie (Paris 6)) for specific use cases: planning, optimization, data processing.

I work with public organizations (CNRS, INRAE, Université Gustave Eiffel, European Union) as well as companies (Euris, Arttic, Fugu).

Pragmatic and structured approach.
