I work for the Swarm Foundation where I recently led the project Wikipedia on Swarm, to make a web3 censorship resistant copy of Wikipedia. Prior to that, I was community manager with the Golem Network. I have a MSc in Law, Anthropology and Society from the London School of Economics, where I focused on the interplay between State Secrecy and Democratic Governance. But my passion for freedom of speech goes way back: my father was a satirical cartoonist and a political journalist, he was often the target of censorship attempts so it’s a family affair.

I am father of twins and a programmer. At the age of 15, I heard that ordinary people can actually program computers, I bought a 1200 page book about C++ and started learning. I sticked with C++ for quite a while, learned Java, went back to C++, learned D, Python, Haskell and eventually Rust. Then I became interested in peer-to-peer systems, experimented with rust-libp2p and found that blockchains could play a major role in mitigating shortcomings of p2p systems. So it happened that I applied at Parity Technologies as a core developer. At Parity Technologies I am driving and implementing major parts of Polkadot's Parachain consensus.
