About Christophe

Looking for a senior front-end developer with Angular expertise for long-term assignments? With over 15 years of experience, I offer my skills for demanding web projects where performance, accessibility, and user experience are top priorities.

I work on new applications as well as redesigns or technical migrations (like AngularJS to modern Angular). I always prioritize code quality, automated testing, and a pragmatic approach that facilitates long-term maintenance and evolution.

I have worked with various teams, including at Edenred and Dassault Systèmes, and on my own music streaming project, Zeffyr Music, which has given me a good adaptability and a global vision of technical and user challenges.

I am looking for assignments in Lyon, while remaining open to full remote work based on your needs.

I am available for long-term engagement to bring stability and expertise to your front-end projects.
