I'm Marcus, a freelance software developer from Berlin.
I'm interested in free software and decentralized, open conmmunication. I have experience working with embedded Linux systems. Both in a commercial automotive context as well as the Android Open Source Project.
Since 2016 I'm involved in the F-Droid project. I maintain various apps there and contribute to client, server and infrastructure.
Currently I'm working on designing and implementing a free and distributed alternative to the centralized and proprietary Google/Firebase cloud messaging system. This project is funded in the 5th round of Prototype Fund. The Prototype Fund is a funding program by the Federal Ministry of Education and Research (BMBF). A very high level project overview can currently be found here: prototypefund.de/project/open-source-push-service-fuer-android-apps/ (German).
