Senior web developer, 10 years in the game, always the right card

Senior Frontend Developer React/TypeScript, I've worked on high-impact projects: Peugeot/Citroën/DS car configurator in 30+ countries, e-commerce overhaul, 30+ component Design Systems. Attentive to code quality as much as to what the user experiences, I like teams where people can count on each other. Since 2025, I've been working with AI on a daily basis.
