I have been a systems engineer since 1999. This was mostly in commercial environments using MS technology.

The last few years I made a switch to OpenSource and Open Content.
Now I am Community Manager of the Zentyal Project: http://www.zentyal.org

Zentyal is the Opensource Small Business Server based on Ubuntu LTS.

My second passion is (OpenSource) ICT in Education.

With a group of enthusiastic members of the 'OpenSource Onderwijs' LinkedIn group I started to organize the Edu-Trac for T-Dose.
