Passionate about software development for nearly 15 years, I especially like programming backend and network applications. Starting by developing C/C++ softwares, now I like to use Erlang, functional programming language for which I have a particular fondness, because of its distributed and concurrent aspects. I understand the need to use tools to improve the quality of my work (eg. unit testing, code coverage, profiling, continuous integration, etc.) and to document it. I daily strive to learn new skills and improve on any I have already obtained.

For over 4 years, I'm actively involved in the development of Yaws, an open-source HTTP server written in Erlang. I'm sensitive to ideas promoted by the open-source development and I am proud to contribute to projets when possible. I owe the different communities that made free-software movement happen many of my knowledge.

Preferred job location: Paris and nearby or remotly.
