I'm an OK developer, don't know anything but superficial about AI or parser combinators or compilers, and most of my work is building pages, forms, APIs and databases and has been for the past decade+.

However, my experience doing that trick is very varied by now; I can do the trick in a handful of back-end languages, front-end frameworks, even native iOS.

So yeah I'm nowhere near a rockstar developer, but I'm experienced, productive, pragmatic, etc.

It won't make me ridiculously rich but I get by. That said, I could increase my income by going self-employed I guess.
