I've completely detached coding for fun and coding for a client/employer. For fun? I write (almost) everything in a single file or however I seem fit, git commit -am "asdf" and use a bare-bones deploy script on a 10$-or-so VPS on which I can ssh and update an nginx config manually if I want to. For work? I jump through whatever hoops the latest CI/CD Kubernetes configuration expects from me, combined with a multi layered microservice architecture and write enterprise-grade Java with Amazon Managed Grafana monitoring in HIPAA ISO SCAMPI compliant environments.

I'm not saying working can't be fun but I have a mental model of what "most fun" I can extract from "coding" and whatever nets me the highest amount of money in the shortest amount of time.
