I'm new to Wikipedia only having joined in June 2022, and not able to put much time into editing, researching and reviewing articles, but I always try to improve the articles bit by bit.
On Wikipedia I mostly edit the article about the local Cologne Stadtbahn. IRL I'm also interested in Computer science/Programming, Table tennis, playing the Piano, the PC games Minecraft and Civilization VI, and general Science and Mathematics, but either I don't feel experienced enough with these topics or the respective articles get a lot of care already from other users.
