Freelancer profile translated to English.

Description

Front-end developer specialized in React and TypeScript, I support companies in the design and evolution of modern web and mobile applications, with a solid technical foundation and constant attention to user experience.

I work across the entire front-end chain: component architecture, state management (Redux, Zustand, TanStack), meticulous integration (Tailwind, MUI, PrimeReact), quality and testing (Jest, Vitest, Cypress), and deployment (Azure, CI/CD). I have contributed to projects for Sociabble, Navya, The Kooples, Cleor, and V33, in demanding contexts for performance, maintainability, and execution quality.

Also a trainer (OpenClassrooms, Le Wagon, IPSSI), I enjoy sharing knowledge and working closely with product and design teams. Available as a freelancer for React / React Native front-end missions, to support product teams, or for high-quality projects.
