On my spare time, I contribute to open source projets, and hack a bit python, django and php.
You can find all the projects I am involoved (sic!) with on my github page
Since I've discovered python in the late 2009, I really like the simplicity it brings to the development. Here are some of the projects I've done using it:
Django is a web framework written in python. I've been working on it while in internship at makina corpus. And also tries to use them for my web related projects.
I've started programming with PHP, it was my third first language (the first two ones being pascal and visual basic).
I've written a dependency injection container and spiral, a web framework in PHP 5.3, with a friend.
I've also contributed (a bit) to jelix, another PHP framework.
