To be honest, "10 years of experience" in this industry means nothing.
I have worked with (and interviewed) A LOT of devs with 10-15 years of experience who can't do a basic fizz-buzz (I'm exaggerating, of course, but really, really weak devs who due to whatever reason didn't bother to improve their skills past what they learned in school in 1980s).
Even $60,000 can be acceptable for a dev with "15 years of experience", if his skills are worth $60,000.
