Resume
Person
I am a very committed person who has an incredible curiosity with everything IT-related - whether it being technical, philosophical, humanistic, legal or thinking outside the box.
I've been around a lot of platforms and worked as a user, programmer, consultant and administrator. Combined it has given me a unique insight into the general use of IT, and has often helped me both to understand the problems, get ahead of them and be able to switch between them.
I have previously been self-employed for a number of years (hardware sales) and am familiar with the full spectrum of business understanding. Many of the applications that I have helped to develop has required knowledge and understanding of financial management.
My big interest and hobby is on the system-administration side coupled with automation (saltstack), CI deployments, scalability and high availability.

Professional life
I have been widely used as an [internal] consultant to find problems / solutions and generally used for sparring in all layers / aspects of the companies I've worked in.
For my earlier (and current) work experience, there is a link to linkedin at the end of this page.
Family and sparetime
Family-wise, I have a wife and three children (3x boys). In my free time I like to bike & experiment with new technologies.
I am lucky to have a good fiber connection @ home and runs various mirrors for open source projects. It is often here I test a new idea (gfs, iscsi, aoe, failover / clusters, ceph) - before I start to implement in testing and finally to implement in production.
I relax the best by reading/researching new technologies/areas and generally just testing myself with various scenarios.
