About
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 operated the core-infrastructure for AS206087 that made our servers reachable via our own autonomous system in the public internet (and helped to migrate and decommission that infrastructure at my previous employer in 2025).
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 that, I got to know the Laravel PHP framework and started to play around with it - one first application can be seen at domainbot.ch. And 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 fire-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.
