My name is Marcin and I live in Poznań, Poland. I'm interested in science and technology and also collect public transport tickets from around the world. I'll gladly accept/exchange them if we meet at some conference ;)
Since July 2025, I have been working as a Software Engineer at Wikimedia Foundation (Product Safety and Integrity team). However, I've joined Wikimedia a few years earlier with real activity having started in waves between 2017 and 2021. On Polish Wikipedia I hold admin, interface-admin and checkuser rights.
