I'm a self taught web dev who loves making tools for podcasters.
I've created Sovereign Feeds, which allows a podcaster to self host their own RSS feed without needing a hosting company. Everything integrates with your own Digital Oceans Spaces, so you own all your own content. Sovereign Feeds is used by none other than Adam Curry, the Podfather.
I've also created CurioCaster, a web based podcast player that uses a ton of the new Podcasting 2.0 tags, like chapter images, transcripts, cast, and streaming satoshis.
