I somewhat followed this:

It's not perfect - you often have to remind it not to write imperative style code and to lean on Elixir conventions like "with" statements, function head matching, not reassigning vars, etc.

Here's one Claude-vibed project that makes me money that I run in addition to my saas, which is Elixir. I'm not strong in TypeScript and this is an Astro static site, so Claude has been really helpful. Backend is Supabase (postgres) and a few background jobs via https://pgflow.dev (pgmq) that fetch and populate job openings and uses some AI steps to filter then classify into the correct categories (among other things, there's also an job application flow and automated email newsletter): https://jobsinappraisal.com

I also "vibed" up this: https://livefilter.fly.dev/todos (https://github.com/cpursley/livefilter) and this: https://star-support-demo.vercel.app/en/getting-started (https://github.com/agoodway/star-support-demo)

I hand wrote very little of this code, but can read most of it - the SQL and Elixir at least ;)

Its not really hard to tell.
