I think your son does not need your help with developing his technical skills, he will do that by himself. What you should be careful is to make sure that he does not neglect other aspects of growing up, like not picking up social skills, not doing enough physical activities. So, this might seem weird, but I think you better not encourage him too much about the things he already like, and should encourage him to do stuff he might be neglecting..
