How to approach a guy as a girl

Salam all, I've (18F) seen this guy who works at a shop I visit a lot and last saturday when I was shopping for my brother I kept making eye contact with him. He's really attractive allahumma baarik and i would say that I'm fairly attractive myself. Obviously because so far I've only judged him by his looks I don't know anything about his education or religiosity but I would be looking to get to know him for marriage and my parents are currently trying to find me someone. I saw him again today and I have a feeling he's in uni and a couple of years older than me so what's the best way to approach him, perhaps next saturday since I'll be going to town anyways without looking like a weirdo or a stalker (because 3 saturdays in a row is lowkey embarassing). I'm thinking to do istikhara and i really regret not checking his nametag just so I could see if I could find any socials and do a background check before making it open that I would like to get to know him. I'd like to add that my parents might be a bit suspicious considering he works at a shop whereas i'm hoping to go to one of the world's best uni's in september inshallah but i think he's doing part time.

any advice would be lovely
