I am and have been working as Datacenter Manager, IT Manager, Product Design Engineer, Linux System Engineer, IT Instructor and Trainer and many other jobs involving Linux, Servers and Datacenters, but don't have fancy names.
From time to time I held various lectures, for example at the Linux Days Chemnitz.
I am an alumnus of University of Technology Chemnitz, where I graduated with a degree in Computer Science.
Most of my projects are about open source, like Debian packaging for a number software projects or working on virtualization and other cloud technologies.
Also while living in the dorm, I spent a great deal of my free time on the maintainance and administration of the Student Network Chemnitz.
I started my professional work as a Linux sysadmin and Perl programmer. Since then I have been working on most Linux distributions and pretty much any application that runs on them.
Currently I am working as Head of Product Development for a small hosting provider.
