Hey there! I'm a software engineer from Berlin, Germany. Since 2018, I'm creating and maintaining privacy focused open-source projects. I enjoy writing simple, maintainable and testable code.
Besides programming, I'm also heavily invested into mechanical keyboards. My daily driver is a DZ60 with MX Clear switches and SP SA Chalk keycaps, but I'm working on a split keyboard (lily58) with Zealios V2 switches.
