Please be mindful that while this all sounds like a great idea and I hope it really exists, this also could be a scam as there is no evidence or any 3rd party that this is a real nonprofit which has been paying 20 people 2k a month to learn to code.
Please don't donate until you're sure this person is using the money as they claim. Attempting to verify their website and facebook leads to some red flags - no pictures of events, just events on facebook with 1 or 2 people attending, no documented proof of the 16 people who are full stack developers. If the non-profit is successful as they've said it is, then if he doesn't want to burn through his own savings (again supposedly) then he needs to seriously do better marketing and proof. Even with those things, I'd be skeptical unless it was independently verified.
