Currently working on a 10+ year old enterprise system where some downstream components are closer to 20 years old. Massive amounts of technical debt. Thankfully my primary work is with a component that's <8 years old, with most relevant code being only a few years old. That being said, with any of these components there's sadly a ton of tech debt. Doing what I can to reduce it, but so much of it is interconnected it's frustratingly difficult to refactor anything without refactoring external systems it works with, as well. Doing what I can for the time being.
