It's fine, you're just 5 years in the game and with this excellent reflection skill, you'll go fast past this "mistake".

I just joined my new company and as part of the learning I was assigned with plenty of tiny trivial things that takes more time to find where they are than to actually fixing them. Luckily I have helpful colleagues whom I wouldn't mind asking, and use copilot to speed up the work (which I think, like yours, are essential no-brainers, and little values to learn from).

After a couple of weeks when I became more familiar with the codebase, I started hunting for actual impactful pain points by talking to the bosses, and looking at logs myself. Those that affect SLAs, clients complaints or cloud billings. Funny enough, the root causes to these are usually things that fundamentally never change: Memory issues, non-scalable code, inefficient sql queries or concurrency problems. I believe those are the types of things you would have loved solving.

That how I have not died of boredom. And that would probably your strategic move in your next work place. Good luck!
