Description

Freelance lead front-end developer, specializing in React and TypeScript, I work on web and mobile applications with high technical requirements.

I support my clients on redesigns and the creation of applications from scratch, acting as a front-end referent, with a strong focus on code quality, performance, accessibility (A11Y), and testing.

In parallel, my Node.js (NestJS) skills allow me to work on full-stack missions, design APIs, and secure front-end/back-end interactions.

My role goes beyond development: structuring, guiding, and bringing sustainable value to products and teams.
