Vom Hirn ins Terminal seit 1998

Hi, I'm Stefan Thierolf and this is my web site. I'm an IT specialist system integration (Fachinformatiker Systemintegration) and work as Global IT Analyst - Network for a global automotive supplier. I lived in the United States (New Hampshire) for about five years and moved back to good old Germany end-of-2018.

You can find a bit more information in my about page.
Some photo albums are also online.
In case I forget some web sites I bookmark them ;)
