About Herve

Full Stack Developer with over 9 years of experience in designing and developing web applications and business solutions.

I primarily work with technologies such as React, Next.js, Angular, Node.js, TypeScript, Java, Spring Boot, PostgreSQL, MongoDB, and AWS. I assist companies in developing new features, creating APIs, optimizing performance, and maintaining existing applications.

I also work on DevOps and infrastructure aspects with Docker, GitLab CI/CD, deployment automation, and AWS cloud environments.

Accustomed to Agile environments (Scrum and SAFe), I work both independently and as part of multidisciplinary teams. I pay particular attention to code quality, application performance, and user satisfaction.

Passionate about new technologies, I also develop innovative personal projects, particularly in the fields of digital health and artificial intelligence.
