Based on my personal experience, no you will not face barriers. As a self-taught web developer in my early 30s (now headed back to school), I was able to get a lot of interviews at small and large companies. There is a lot of demand for good software developers. I do not think age will enter into the equation at all.

Yes I'm sure there is age discrimination in the industry and you might have he misfortune of encountering it. But based on your other comment, you seem to have a determined attitude which is great. Now quit inventing problems for yourself that don't exist and go spend your time doing something more worthwhile.
