Thank you! Happy to hear you found it useful. For Ecto I've written a brief primer https://brooklinmyers.medium.com/ecto-with-phoenix-in-4-minutes-9b7c447055c6

And also about how to compose queries with named bindings https://brooklinmyers.medium.com/phoenix-elixir-chain-composable-queries-with-ecto-named-bindings-7a3ec5ba93

If there's anything not covered in there let me know! Always open to suggestions for writing topics!
