Status: up and running


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 or Kubernetes clusters.


Provisioning with foreman or configuration managment and automation with puppet or ansible.


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


Proactive security by monitoring system resources and services with icinga2 or collect metrics and alert with Prometheus.


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