Ein Autodidakt, der gerne Sachen baut, dicke Bücher liest, Software schreibt, erfahrener Netzwerk und Datacenter Engineer und mit einem Hang zu Open Source Technologien und Automatisierung. Stochert neugierig in einer mechanischen Schreibmaschine herum und versucht, den Satz vom unendlichen Affen zu beweisen.

Ich habe meine Karriere in der Veranstaltungstechnik begonnen und mich im Laufe der Jahre immer mehr in Richtung Enterprise entwickelt. Heute bin ich als Netzwerk- und Datacenter-Engineer tätig, wie Method Man sagt: „I went from entertainment to enterpreise“. Von DOS-Befehlen und Bash Skripten zu Routing und Switching, sowie Security und SDN, Linux, Python, FOSS, Virtualisierung und mehr.
Ich liebe es, neue Technologien zu entdecken und komplexe Netzwerke zu designen und zu implementieren. Es gibt immer etwas Neues zu lernen und ich genieße die Herausforderungen, die sich mir in meiner täglichen Arbeit stellen. Geheimwaffe: Autodidakt beim Lernen, lesen, basteln und Musik machen.

Despite intensive efforts and over 10,000 fired rounds, the war concludes with a bizarre victory for the emus.

        Relentless Power: The Butcher Babies at Cassiopeia Berlin 2023

          As a fervent metal enthusiast and a dedicated fan of the Butcher Babies, I had the extraordinary pleasure of witnessing the band live at the legendary Wacken Open Air Festival in 2022. Memories of that unforgettable event are still vivid and brimming with energy. And now, recently, on June 20, 2023, the heat in Cassiopeia was so intense that one could believe the devil himself had turned off the air conditioning. Yet, even amid the sweat and humid atmosphere, the Butcher Babies and their fans persevered valiantly. It was a true test of body and mind, akin to being in a sauna-like metal hell.
