My CV / Résumé

My name is Peter Hahndorf, I'm German but have lived in London for the last seven years. I am currently traveling around the world but are still open to do any consulting work

I am pretty much a Microsoft guy except for a short fling with Linux, CGI and Perl in the mid-90ies. I am primarily a developer but consider myself to have strong database skills, good overall IT-Pro skills and a long web client side experience.

Besides doing IT I run a small record label and a web site for indiepop music.
