Software builder, engineering lead at Flashbots, dad of two, based in Vienna, Austria 🇦🇹
I work on MEV infrastructure and help keep Ethereum decentralized - currently focused on BuilderNet, MEV-Boost, and distributed block building. Much of what we do is open source software, open research, and open standards.
For 20+ years I've been part of open source communities across Europe - from Metalab (one of Vienna's first hackerspaces), to OLPC, Google Summer of Code, and the Chaos Computer Club.
