Profile

I've had practical experience with programming since 1982 and I am very experienced with network and Unix since 1986. Professionally I am a strong technical trouble shooter, and I like a challenge. In projects I typically have the role as the technical specialist, who can offer advice and support wrt. the technical quality of a solution and in consideration of other technical solutions. I would in the future like to keep my technical focus but I am open for a cordinating technical role. As a person I am calm, active and helpsome. I am used to having responsibility for my own assignments, but I also thrive in an open interplay, - for example a solution to a technical problem requires the collection of information from all the involved parts. My future professional interests lies within large networks, security especially wrt. wireless technology. I would prefer to work for a large or middle sized company.

General

In my spare time I am also interested in IT, doing small projects in areas where I have little expertice.
I enjoy music (jazz, blues, rock) and, I've been a voulontier for the Roskilde Festival establishing part of the backstage inferstructure (1997-2006) and working on the Arena Stage (2007 - 2015), I liked the size of the project, where a lot of things must play together, the tasks must be done by a fixed deadline and the social interplay.
I enjoy spicy food, horseback riding and I play role playing games and strategical computer games.
I read many novels in english, - primarily science fiction.
