> 15+ years writing software, web, and database code. Am I doing OK with 80k/year

That's about what I was making with less than two years experience at an extremely small non-profit with a very limited budget as their full stack developer - so yeah I think it's safe to say you should/could be getting more.

[N.B. this is in Boston which probably has a higher cost of living / average wage...but still nuts someone with your background/experience is making what I was at the non-profit]
