It sounds like you have rare skills. You certainly could learn to be just another web dev, but I'd take a shot at seeing if you can use your current skills remotely - you are likely to earn more. I'd probably learn Python/Django and numpy. They gives you the ability to do solid backend web dev, and should open up plenty of jobs. Python is also often used to tie together high performance c code, so you may be able to find work that uses both your new skill and your old.
