Software engineer for a company that had made the work for clients extremely customizable, to the point that for most of the day I'd just be going through "GUI Wizards" to deploy a new instance for a new client.

Almost every tweak was just a tweak in a settings file or with the UI, and almost no new code was written.

Kudos to the devs building this system initially, but horribly boring for the devs that came after them.
