My name is Wojtek, I live in Józefów (suburbs of Warsaw, Poland). I’m an active editor in Polish Wikipedia since September 2009 and an administrator since 2012. I studied Chemistry (Explosives and Pyrotechnics) at the Military Technological University in Warsaw. I serve as a police officer. In Wikimedia Projects, I mainly deal with topics related to chemistry (Polish Wikipedia, Wikidata and Wikimedia Commons).
