Description

Fullstack JavaScript Developer with over 9 years of experience in designing and building high-performance web and mobile applications. Expert in React, React Native, Node.js, and TypeScript, I work on high-impact technical projects in various sectors: e-commerce, finance, public sector, and SaaS.

Accustomed to taking on complex or blocked projects, I collaborate with product teams, designers, and technical teams alike. My approach combines technical rigor, product vision, and the ability to upskill teams. I have supported companies like Hermès, PMU, BNP, Kyriba, and Raja in their critical overhauls, the implementation of design systems, scalable architectures, and fluid development processes.
