I have no experience in love things, but I can give advice out of logic and so on.
I'd wait a bit and try to casually talk with him more and more. Relationships do take time. That's of course if you have the time. If you don't, try talking to him once and ending it with "You're a nice guy, can I give you my number?" Then you have to let him handle it. As far as I've experienced it, guys like to have matters in their own hands.

Was that helpful? I don't know... don't hate me if it doesn't work... *cries*
