After a course in industrial computer science at CNAM (Conservatoire National des Arts et Métiers) I went to PHP completely by chance for a professional need.
After I became a PHP developer, and I must admit I'm a PHP enthusiast, I expanded my expertise to SQL databases (MySQL / MariaDB in particular) and a little bit of Linux sysadmin.
After a few years I became project manager and attended several training courses (project management, team management, creation and automation of tests, ...).
