I've been editing Wikimedia projects since 2005 when I started contributing to Polish Wikipedia. I have been an administrator on Polish Wikipedia (2006–2018) and Wikimedia Commons as well (2012–2020).

Currently mainly editing Wikidata.

Board member of Wikimedia Polska (2018–2020).

I've been technical coordinator of the Wiki Loves Monuments (2013, 2014), Wiki Loves Earth (2015), Wikiwakacje (2016–2018) competitions in Poland – if you have any questions about it, feel free to ask!

Since 2016 member of Wiki Loves Monuments international team.

I created and maintain the Commons upload tools, VicuñaUploader and Pattypan.
