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.
