It is an impressive list of items that you have been able to do. It is very practical and something a college/univ education might not provide.

At some point in life (there is still a lot of time for you) you will have to make a decision, whether there is some benefit going to school to improve your theoretical knowledge. The hard part is knowing if that is useful for you :-). It is becoming irrelevant each day with initiatives like coursera/udacity.

Wishing you all the best for a great future ahead.
