Together with my wife, our kids and our dog, we’re living in Hochdorf, Switzerland.

I used to build websites and web-applications at internezzo with TYPO3 CMS, Neos CMS and Flow Framework mostly. Then transitioned into the infrastructure and operations part over time, running a lot of Linux based servers, the underlying virtualization platform and the network / connectivity side.

Along the way I specialized in operating our Puppet infrastructure, running DNS servers, Mail servers, Gitlab and CI/CD infrastructure, Nginx Webserver-configuration and monitoring. Since 2023 I operate the core-infrastructure for AS206087 that makes our servers reachable via our own autonomous system in the public internet.

In May 2025 I joined Ops One as a DevOps Engineer and will continue on this journey of operating web-infrastructure in one of the other ways.

Besides work, from time to time I develop smaller things and sometimes release what I’ve built as open-source software. And I give back to existing OSS projects by writing about it, testing, submitting bug-reports, creating patches, …

I’m still somewhat bound to the TYPO3 Project even after becoming rather inactive the last years. In 2024 I decided to become a community member of the TYPO3 Association to give something back - and get the opportunity to vote at the annual General Assembly.

I’m also engaged at the local firefighting-department and was responsible for all the equipment from 2014 to 2021. Since 2022 I moved more into training others in different areas from extinguishing fires, handling ladders, safety in general and first-aid.
