Devs, what do you find most repetitive in backend development?

Hey everyone! This is my first post on Indie Hackers so I hope it's a meaningful contribution. I'm currently working on a project (https://visual-backend.com) which to sum it up briefly, is a desktop app that aims to make backend dev more efficient by getting rid of the repetitive bits like boilerplate code set up, allowing you to immediately focus on the business logic of your server.

Anyways, I'm still learning about the different challenges that all types of devs face when it comes to this area, so I'd love to hear from everyone: What do you find to be the most repetitive part about backend dev and how big of an issue is it for you?

Here's my answer:
I find that writing a CRUD function for a REST API can very repetitive, or at least the set up is. I always find myself doing the same process of copy pasting some boilerplate code, configuring the router, and occasionally handling auth before actually starting to write the logic of the function.

This can get quite annoying when I'm making a basic backend API with some CRUD functionality, mainly because there's not much complexity to the functions, and so I'm pretty much just doing the same thing under a different context many many times.
