Sounds similar to my kid, who has improved tremendously since we got meds (in retrospect I wish we had not been resistant to them earlier) and EF coaching skills (the latter were via the school but I understand many schools do not do this well).
there is no need for a “special camp”. My kid has adhd and is on the spectrum, and did both architecture and engineering summer workshops -and was definitely not the only one with these there. Enjoyed both of them content wise, socially one was much better than the other.
but I will repeat, the EF issues need to be addressed before college. There won’t be any handholding /anyone to be on his case about assignments there, and as you’ve already seen, a superb memory only goes so far as the workload gets bigger and bigger.
