Ask HN: What are some “trivial” achievements you feel satisfied about?

Programing achievements don't have to be revolutionary. What is something "small" that you've done that makes you happy or proud?

I named the message broker microservice of a big application "Lepus" (rabbit in Latin, because we were using rabbitMQ). Seems trivial but this happened years ago and I'm still happy about it.

What are yours?
