Not the person you're responding to, but I also quit my job and started a company that uses Elixir for internal stuff.

It's overkill for some of our problems but it's working fine! We make mistakes, but they're mistakes we'd have made with most other languages.

I did have to buy Pragstudio licenses for anyone using Elixir on the team. I'd prefer a few books, but most Elixir/Phoenix books don't seem like they're keeping up with the rate of change.

Pretty good. The company is jumpcomedy.com and I'm making less money but am much happier. Pair and mob programming have been hugely helpful in sharing learnings and patterns. We only have three developers - all remote. One very nice surprise has been how amazing LLMs are with Elixir, something about a clean functional language maybe, not sure.

Getting feedback directly from production has been helpful too to tell us when we didn't think something through. We don't use branches, everything is a commit to main and every push is a production deployment so all three of us are in the loop on what each other is doing.

Didn't really buy any books but testing and trying things out in LiveBook has been huge to learn the nuances of the language. The LiveDashboard has been great in monitoring things, especially the PostGres plugin for it. The Discord community has been very supportive as well, and the Elixir Forums as well.
