I'm 33 years old and I guess I've been a computer geek since I got my first computer on my 10th birthday (a Commodore 64). Started using Linux based operating systems more than 15 years ago (1992), later I moved on to other flavours of UNIX and then back to Linux again.
While studying at the University I was actively involved in the computer society there, both in administrative positions and as a system administrator (UNIX systems; Linux, Solaris, Ultrix, etc).
I also worked within the student union doing course evaluation and worked as a student representative on the board responsible for the D programme (see below).
I'm a quick learner and enjoy learning new things. I work well both as an individual as well as within a team and help things get done. Since a few years back I've also had a lot of experience of people management, a challenging aspect but one that I've enjoyed working with.
All skills below are listed in order of proficiency/experience. The list isn't exhaustive.
