In all likelihood, the best use of your skills is to make money and then donate it. Find a good charity. Of course with charity you want a quality charity that spends on the intended target and not the management or ad agency. My 2 favorite are unbound and salvation army.

If you feel a need to have a lesser, but more direct impact, find a charity / church et el that you care about. I am sure in this day of the remote worker, you can do something for them.
