Hire me

Below you will find a brief listing of my skills/experience. A complete CV is available on request. I am available for freelance work.

System administration

15 years of experience administrating heterogenous networks with unixoid servers (FreeBSD, NetBSD and Linux) and unixoid (FreeBSD, Linux) and Windows clients.
Buildout and day-to-day operation of a large scale data center
Half a year of experience working for a large ISP (operations/roll-out)
Solid knowledge of TCP/IP networking, including hands-on experience with Cisco and Juniper hardware.
Design and implementation of security concepts for networked environments

System adminstration related scripts in Perl and Shell
Distributed computing using PVM and MPI

I hacked up a fair amount of code over the years. Here's what's available publicly:

cloudnets-framework	The CloudNets Network Virtualization Framework. I contributed a fair amount of code to this system and polished it up for public release. You may in particular be interested in the Transit Link Negotation Protol component I implemented in the course of my Bachelor's thesis. It keeps track of VLAN tags and VPLS configuration parameters and hands them out as required for virtual transit links between providers.
Github	My small concession to the 21st century. I have to admit, it is rather useful for submitting the odd patch.
My private code museum	A rather dated collection of small scripts and utilities that hasn't been updated in years.
