I'm a TeX enthusiast. After studying mathematics in Jena and Hamburg I've been working as IT Admin and Communication Officer onboard of cruise ships. Pictures of those years can be found on twentyknots.com.
Now I'm employed as a IT Network & Security Engineer for a cruise company.
For some years I've been working as a freelance programmer, since many years I'm working with LaTeX. I'm a friend of Linux and Ubuntu user.

- LaTeX.org with its forums
- TeXblog.net, where I publish some ideas and news from the TeX world
and I'm an active user in several math forums such as on matheplanet.com.
