About Cédrick

Trained at École 42, I acquired strong autonomy and the ability to thrive in demanding technical environments.

Today, as an independent developer, I am involved in the design, evolution, and deployment of web platforms and products with React and Next.js, in SaaS, high-traffic, and Web3 contexts.

I pay particular attention to code quality, performance, maintainability, and collaboration with product, design, and back-end teams within agile dynamics.

Currently open to new missions, I am looking for technically stimulating projects with real product challenges and close collaboration between departments.
