Does my coworker like me?

So this guy is kinda new. We share an office and he is always saying funny things and makes me laugh. He also seems to be wherever I am during the work. In the evening and my day off he texts me but it's mostly work stuff, just talking about the day. He uses a lot of emojis and gifs when he texts but again it's mostly work stuff. He is very shy at work and doesn't seem to talk to many people. We are both middle age. What do you think?
