+Heya! I'm Beto. My preferred pronoun is they/them, but he/him is fine.
+
+I'm a software engineer working on [Apache Superset](https://superset.apache.org/), and I make music under the name [The Fishermen & the Priestess](https://thefishermenandthepriestess.com/).
+
+I'm a big fan of open source and the fediverse. I run a few ActivityPub instances:
+
+- [lemmy.studio](https://lemmy.studio/), a Lemmy instance focused on music-related communities.
+- [photos.thefishermenandthepriestess.com](https://photos.thefishermenandthepriestess.com/), [social.thefishermenandthepriestess.com](https://social.thefishermenandthepriestess.com/), and [songs.thefishermenandthepriestess.com](https://songs.thefishermenandthepriestess.com/) are my Pixelfed, Pleroma, and Funkwhale instances, respectively.
+- [2c.taoetc.org](https://2c.taoetc.org/) is my personal Mastodon instance.
+
+I also run a small [music label](https://slothcore.bandcamp.com/) that started as a joke.
+
+Let's do this!
