You're biggest issue will be getting selected for an interview. If I'm recruiting it's generally for a specific full stack developer. i.e. Ruby on Rails. Personally I would see your background as an advantage but I'll still need to be able to see that you can hit the ground running. So ideally you'll need a project on your CV targeted at the recruiters development stack. Perhaps an open source project or a side project, or freelance on upwork. You're age is an advantage, don't forget that. We grow wiser every year.
