These experiences have allowed me to work on stimulating projects, ranging from creating showcase websites to complex architectures.

Specializing in TypeScript, React, Next.js, and NestJS, I also master Docker, AWS, and DynamoDB. My goal is simple: to support you in the realization of your projects by offering robust, aesthetic, and needs-adapted solutions. Let's work together to bring your ideas to life!
