Full-stack developer sounds sexy but sort of doesn't exist? Not in the way it sounds anyway. The great full-stack developers I have met have two things in common: 1) over 8 years experience in software dev AND 2) they still have a preference for what they like to work on - back-end or front-end. Yes, they can go up and down the stack, no they would rather spend their time coding back-end (or front-end), thank you very much
