It’s hard to be much of an “expert” this early on in a career (though not impossible), but I do iOS work. There’s a lot of context in the previous article that I linked if that’s what you’re looking for. I have a pretty standard CS degree from a small school. And no, I don’t think I’m a 180 IQ student. :)

I have some friends across the pond that tell me how much higher salaries are in America. I don’t think it’s a secret :)
