I am a Free Software hacker, 28 years old, living in Paris, France.
For the past 10 years I've been involved in several Free Software projects and developed a lot of software. I also spent several years working as a Linux system administrator and engineer for various organizations and companies.
Nowadays, I'm mainly interested in X11, functional programming languages, massive data storage and computing scalability.
You can read my resume online. Feel free to contact me by e-mail at julien@danjou.info.
