Presentation

My name is Gerardo Exequiel Pozzi (djgera). I am from Buenos Aires (Argentina), my year of birth is 1982. My areas of interest are: low-level programming, theory of languages and mathematics in general.

I am using Arch Linux since December of 2008, my original distro was Slackware Linux since October of 2001. I like helping the community in what it can within my reach, for example reporting bugs and feature request, new ideas, packaging, etc.
