Guys, Would this even be considered hitting on someone?

New co worker started working at our company, I am older but we are both university students as well. He will be going to Spain for exchange program and he needed to write something in Spanish, he doesn’t know any and I am fluent. He asked me if I could help and I said expecting him to just to write something for him to send via email or helping at work when it slows down. But then he mentions doing it after work. Although I am fluent there are many other resources in my opinion that could translate for him so I am confused. I do catch him looking at me sometimes, especially today when I was using teams to chat with my coworker and we started giggling and laughing. All the sudden he pops over his head around the column that blocks us and I noticed him glancing a peek at me smiling. Is this a good sign?
