About me

I finished my education at the Max-Planck-Institut für Informatik at Saarbrücken. The main topics of my studies were complexity theory and algorithmic geometry. The title of my diploma thesis is "An Implementation of an Algorithm for Convex Hulls". There I got to know (and use ;-) various programming languages (C, C++, Pascal, Java, different assembler languages), especially on Sparc-Clusters under Solaris and SunOS.
Through my interest in networking and the internet I aquired a great knowledge in this, especially about Cisco routers, but also other manufacturers, and the used network protocols, procedures, and conventions. As an adminstrator I also know various programming languages (perl, bash, php, C, C++, java, etc.)
In my current position I am responsible as an internet expert for the network and system infrastructure. This starts at planning and building and spans security analysis as well as survaillance, maintainance, and documentation. Amongst other things I installed a comprehensive and proactive monitoring system and took responsibility for external connections (with Ripe, peering partners and BGP-configuration). Also the network structuring and the reliable operation belong to my duties. With this I gained much expirience in planning and building high capacity and failsafe networks and servers. Coordination with developers in various projects is part of my task as well.
Privately I work on the m68k-Port, iPaq, and ppc port of Linux, where I use a slightly modified Amiga 4000 and Apple iBook. I also wrote some device drivers for Linux and patches for FreeBSD. You'll find a resume of this below .
