Save time as developer

What tools or tricks do you use to save time as a developer?

I'm talking about things like avoiding to write tests, write code that can be reused for all projects and so on...

Personally I have a git repo that contains all the base code to start a new project (user auth, stripe, emails sending, etc), plus I created a script to create and deploy new servers in less than 10 minutes. Plus, of course, I don't write any tests and use AI copilot.

I'm curious to know if there is anything else.
