Description

Experienced Backend Developer | Java · Spring Boot · 6 years of experience | Available (France & Switzerland)

I am a freelance Back-End developer with +6 years of experience, specializing in the Java / Spring ecosystem and the design of robust and scalable solutions.

I work on technically challenging projects: design and security of REST APIs, batch data processing, containerization, and deployment. I have worked on both greenfield architectures and existing codebases requiring evolution.

My background:

6 years of assignments in IT consulting firms and direct client engagements, in France and Switzerland.

I contributed to projects in the public sector (State of Fribourg, City of Lausanne via Talan) and in the private sector (CEGID, industrial SME).

Very different environments that have forged my ability to integrate quickly, understand business needs, and deliver autonomously
