In a nutshell

Entrepreneur, IT oriented, sport-aholic & food adventurer. C.T.O. of Capteev.
My confort zone is web development - PHP with Symfony 3 and MongoDB, but what make me work with passion is to build projects I believe in with team from scratch until success - or the end of the adventure. Always hungry, never afraid of passing obstacles I never faced before.

Graduate of Ecole Centrale de Lille 2017 (Lille, France). Master's degree in Web Engineering. Courses in e-business, project management, web marketing, SEO, financial audit, and of course development. I'm interested in many fields building projects around Web 2.0 !
