Jean-Marie Cléry, Freelance developer and trainer at the Multimedia School
Passionate about web technologies since my youngest age, I first started programming with PHP, until the "revolution" of JavaScript: a language that definitely appealed to me because of its flexibility and the multiple possibilities it offers client side (gaming, 3d, websockets, webrtc, ...) and server side with Node.js Today, I occupy half part of my time with Freelance projects, and teach JavaScript (all levels ) in training organizations the other half of the time. If you have an innovative web project, or simply need JavaScript expertise, do not hesitate to contact me!
