He is 6 years younger: could he like me, could we work?

He is 6 years younger: could he like me, could we work?

I met him at an event, we became friends then. We don't really talk often, I work, he's in university. He's given me mixed signals over the past year... from being 110% present for me, to cancelling last minute... I have a stupid crush on him which I believe I've managed pretty well so far. When I was in university I didn't want a relationship because I was too busy and too focused, so I wonder if that's just the case for him.
I guess I'm asking, how should I move forward?
I don't wanna be forceful, especially if someone is not actually interested.
I think we have enough in common that I can accept being casual friends for now.
But I also do have some interest and it's sort of there annoying me in the back of my head xD
I think he's interesting and I'd like to know him more though before I can actually say i'd date him.. but I don't know how to develop a friendship whilst having a greater interest.
What would you do in this situation?
just fyi, we are both in our 20s
