I think we must've worked at the same place. I took a job at a jira feature factory working on an aging, ossified code base. Literally, it was using the same tech I was using 10 years ago, almost exactly, except it was new back then.
I spent most of my time writing design documents, doing code reviews, and shepherding my relatively small changes through review. Something I could've banged out in a week would take months due to all the review and processes.
