Hi, my name is Gerald and I am a software developer from Münster. On the internet, I usually go by ubergesundheit. For fun and recreation, I like to try out new programming languages and technologies, tinker with programmable gadgets and embedded systems, cook and eat tasty recipies and read or watch science-fiction. In Münsters Code for Germany division I voluntarily create civic tech with open data. I'm really interested in technologies and topics like Linux, containers, container orchestration with Kubernetes, decentralization and self-hosting. My secret weakness is owning and trying out mechanical keyboards.
You can find me on GitHub, and Keybase. You can also write me an email.
