Should I text a shy guy who liked me at uni?

It was really apparent that he liked me back then lol. But he liked something I posted recently and I’m wondering if I should just text him in a friendly way and ask how he’s doing/how his career is going etc?

I am interested but I also never make the first move! From what I remember, he was painfully shy at university.

Should I just do it and text him? I’m scared of rejection also.
