Oh nice, I really like the idea of introducing ourselves! Maybe we could even create an official thread for that purpose. You can add a user description on Discourse, so adding it there is probably nice, too.
Looks like you both started working on AntennaPod a lot earlier than me. I did my first pull request in 2016 (statistics screen). I began contributing regularly in 2017. After meeting the old maintainer (mfietz) in person at the 34C3 congress, I somehow became the maintainer.
By the way, the C3 congress is really nice if you have time between christmas and new year. There’s usually an F-Droid meeting with many developers of open-source Android apps like K-9 Mail, Conversations, Öffi, Nextcloud, MicroG (and AntennaPod). Not sure if it will be the same this year, though.
