A Pro in all about Linux. This passion has driven the deepening of my understanding of Unix systems for about a decade now. No Linux challenge is too much for me. I've been a Gentooer for over 5 years now.
Over the years, apart form Gentoo Linux, I've worked with FreeBSD, OpenBSD, several major Linux distributions such as Ubuntu, Debian or Fedora, and some other unices, such as SunOs, Android, and embedded systems such as OpenWRT, DD-WRT and Opie.
