My biggest dev ambition is to continue supporting and improving the same codebase for at least 5 years.

That codebase is already 6 years old and going strong.

How bad/good is the codebase? Is it for work?

@rantsauce It's my company codebase. I am the technical co-founder, meaning I wrote it alone the first few years.

The quality is ever improving. The recent part are quite good, though not perfect. The oldest part are not that great, but not quite awful.

That's code I wrote when I was fresh out of education, and under lots of pressure to deliver, so I'm overall quite pleased with the current state of affair.
