About Sébastien

Passionate about development for over 14 years, a geek and a great traveler, I have had the opportunity to work on numerous subjects throughout my career, as well as personally to satisfy my thirst for curiosity during wild evenings on SDZ (for the older ones!) with Mathieu Nebra's courses, stackoverflow, or developez which were my bibles.

With 6 years of professional experience, I am looking for a mission in back-end development or on the blockchain.

My preferred languages are Java (Spring Boot) and Python, even if C/C++ will forever remain in my heart, and I also master several other backend languages such as NodeJS or Php.

My favorite frameworks are Spring and Django, one for stability, the other for development speed.

I don't consider myself an expert in any specific language or framework, I am a passionate developer, I have spent half my life behind a terminal and an IDE, I love to touch everything and learn new technologies on an interesting project.
