editing since 2004 mainly in Wikipedia in German, but also a lot on Commons, and sometimes Wiidata.
My thematic areas I'm editing in (in de-Wikipedia) are in a continuous proess of development. In recent years I've edited mostly articles around Portuguese colonial history in Africa (especially Mozambique), different aspects of Portugal (politics, railways), politics of the European Union (mostly on Members of the European Parliament), and modernist architecture
Professionally, I have been working for the structures behind Wikipedia as a paid staff member/contractor since 2014. From 2014 to 2020 as Cornelius Kibelka (WMDE) at Wikimedia Deutschland, from 2020 to 2022 as CKibelka (WMF) at the Wikimedia Foundation. Both accounts are no longer active.
