Firstly, I wouldn't suggest you make du'ah to Allah(Swt) to bring you too together. You should make du'ah to Allah(swt) to bring you two together if there is kheir(goodness) in it.
Secondly..There's a thousand ways to go about this IMO.
One would be,tell someone you trust (if it is a man, he has to be a mah'ram to you, like an uncle,brother,father...) how you feel about this person, and if it possible for this to go somewhere Halal. If you are too shy to express your feelings publicly, chances are you are too young to get married(unless you are by nature a shy person, but then again, in these situations, one must speak up, even indirectly, if they hope for anything to happen.)
if the man is religious as you say, he will not be weirded out by the news that some sis has noticed him and wants to get to know him/his family better, to see if there is a future with him.
I don't see anything wrong with the girl(or,more specifically,the girl's "side") to approach the guy. It doesn't always have the be the other way around I mean, if it is done in a halal manner.
So if the guy's looking to get married he'll probably respond and things can move on from there. If he thinks he's too young/doesn't want to right now because of studies or something, then in the future he'll maybe remember you...And like anony2 has said, if you're meant to be with him...
than nothing can stand in the way!
