Status: up and running

Everyone operating a computer-service loves this message and I’m passionate about keeping it up and running.

I have several years of experience as professional system administrator and more than 15 years as hobbyist using GNU/Linux.
Currently I’m orchestrating the IT infrastructure for schools, build networks and scalable web-services.
One of my biggest interests lies in virtualization and task-automation.


Here is an overview of the things I’m good at. I’ve used all of the following technologies in production environments for some years. Still I’m constantly striving to improve running systems and use new technologies where applicable.


Administration and maintenance of GNU/Linux and Unix systems.


Everything from a single docker container to scaleable application stacks with rancher.


Provisioning with foreman and configuration with puppet.


Planning and implementation of networks including firewall setups with pfSense and OPNsense.


Proactive security by monitoring system resources and services with icinga2


Reviewing and optimization of running systems as well as general consultation.
