Doesn't that work against you? Like, I imagine that at some point you want to get a raise, so your manager has to sell your work to other managers... and they are not gonna pass around links to your pull requests/commits. They most likely want to see epics/tasks in Jira or something similar.

I mean, finding a Jira epic/project where to fit my ticket is not the hardest part of the job tbh. Also, depending on the team and your experience, loosely fixing things here and there can be a red flag or totally the opposite (e.g., I've seen how juniors or people in general with less than a decade of experience get punished when they start fixing random things here and there. On the other side seniors or staff engineers get kudos for fixing also random things but in less volume and usually more tricky ones).

Having a ticket to back up your work is never going to hurt you, though.
