Unfortunately I don't do anything nearly that sophisticated, I honestly barely even know Elixir, I had just used it a little bit at a previous job and thought it would be a nice choice to try for the web server part of an application I was building.

I mostly use Claude in that repo for controllers, DB access, and front end via heex templates, often with LiveView. I find it can get a bit mixed up with heex stuff occasionally given the weirdness of nested code into the HTML and all that but I think on pure Elixir it usually does a good job.
