Freelancer profile translated to English.

Description

Former developer at CERN specializing in web application development, I have carried out numerous freelance web development services for various clients such as universities or SMEs on very heterogeneous projects.

Thanks to this experience, I can quickly adapt to projects of any scale and on many backend and frontend technologies: I have skills in Java/kotlin (Spring Boot), PHP (with or without Symfony) as well as Js/Ts (NodeJs, NestJs and React).

My main goal is to provide you with a perfectly functional result with meticulous, easily maintainable work that is open to new developments.
