I am a senior software engineer. I refer to my current project as a chain of side quests.

All I wanted was to optimize a batch operation in our system. That needed a feature of a new version of our database. So I upgraded the database. But to utilize this, I needed to use a newer version of the db driver/sdk. The one we use is tightly coupled to the object mapper. So I needed to start upgrading the object mapper first. That is a major version change which breaks a few different spots in our system I then tackled one by one. I am still not done.
