You don't put age on a resume.

You may leave out earlier projects and graduation date on a resume; even if you don't, speaking as someone who has interviewed, you don't really look at the years. "Oh, they worked at X, Y, and Z", not "Oh wow, they've been doing this professionally for twenty five years, they're at least in their mid 40s". Especially if it's a newish technology. This person has ten years of Javascript experience, two of that with Angular, awesome, we need a front end dev familiar with Angular. Holy crap, they're in their fifties; they just didn't list, or I didn't notice, all the non-relevant experience.
