About Me
Hi - I'm Christian, an IT specialist with a strong penchant for technology, books and politics.
Professionally, I've been working as a Linux system engineer since 2024, and I continue to pursue my fascination for open source technologies and Linux systems in my free time in my Homelab.
I like to deal with topics such as network architecture, virtualization solutions, backups and my growing smart home, always looking for optimal or new technical setups that work reliably and efficiently.
In addition to my technical expertise, I am also an active blogger and podcaster. I run my own blog where I write about IT, technology and sometimes nerdy topics like Star Trek. I'm also part of the podcast Chevron 10, where we passionately discuss and dissect our favorite series Stargate SG-1.
Politically, I'm heavily involved in issues close to my heart and have a soft spot for the nuances of privacy and digital sovereignty. Whether professionally or privately, I try to make the world of IT a little bit more understandable and accessible.
My hobbies range from technical tinkering in the Homelab to gaming on various platforms and lately a lot of reading and listening to books, mostly but not only science fiction.
