I specialize in system and server administration. I am also interested in programming and web development, with a strong focus on practical applications and automation. My work mainly involves open-source solutions and self-hosting. Amateur radio enthusiast (favorite band: 40 m, 7.0-7.2 MHz) and mesh networking fan. Open to interesting collaborations - feel free to get in touch.
