Guys how can I drop hints to a guy at work that I really like him?

I know crushing on a coworker isn’t always ideal but I’ve had feelings for him for like a year now.
What are some ways I can make it very obvious to him that I like him?
We don’t spend a lot of time together at work just have brief chats but we have loads in common and we do flirt and message outside of work -

but I wanna take it a bit further and see how he reacts just now sure what to do…
