Even with the single "job" like developer, putting out okay code that's well documented and tested is probably more valuable than just putting out very good code with barely any docs and tests.
Especially if you add some social skill to figure out what exactly needs to be built instead of taking ticket comment at face value then figuring out author of request had something else in mind once it lands in test environment.
I'm not the best programmer there by a long shot. I didn't grow up programming at the age of 10. I don't have a CS degree.
But then I thought how nobody has the same experience as I do. I have a mixture of things I'm good at that make me unique and valuable.
