About Nassim

Java/Angular developer with 4 years of experience, I have worked on critical projects for Airbus Helicopters, Groupe BPCE, and the Government of Monaco.

My work-study missions were directly operational: migration from AngularJS to Angular 17, Spring Boot 3.x development on government applications, API performance optimization, and response time reduction. No gradual skill ramp-up, I was integrated into production topics from the start.

I am available immediately for a fullstack position in full remote or hybrid in the Aix-Marseille region.
