Description

Senior Java / Spring Boot Developer — 10 years of experience in banking, insurance, and media

Proficient, autonomous Java back-end developer, quickly operational on your projects.

For over 10 years, I have been involved in projects within the IT departments of large corporations (Société Générale, Generali, Agence France-Presse) for application creation, modernization, and maintenance.

What I do concretely:

- Design and development of REST APIs in Spring Boot (Java 8 to 21)

- Migration and modernization of applications (Java 8 → 21, Kubernetes/AWS containerization)

- Implementation and maintenance of CI/CD pipelines (Jenkins)

- Integration of AI tools (GitHub Copilot) to accelerate delivery

My mindset:

Committed to quality: unit tests, code reviews, clean code — to ensure the project remains maintainable over time. I integrate easily into an Agile team (Scrum, SAFe) and quickly gain expertise on complex existing systems.

Feel free to contact me to discuss your needs.
