As somebody who has 20 years of experience: I think I'm pretty good in my specific niche; there's wide areas to the sides of it where even if I haven't done that before I could get up to speed pretty rapidly; and there are some kinds of software work that are so far out of my field that you'd be much better off going for somebody with 2 or 3 years in that area rather than me. Programming is a massive field these days, and it's not all 100% interchangeable.
