Was my coworker throwing out hints that he is single/interested?

hi! at work today my coworker and I discussed snowboarding and I said how I want to go over this winter and learn as I have never been and he was saying how he loves to snowboard and his family even has a joke that it is a requirement to date him to know how to snowboard. A little prior I was mentioning how I would love to go someplace like mammoth and not be on my phone and be out in nature and he mentioned how his phone is dry he said something like "yeah no one needs me i wouldn't even get any texts over a few days". also was this flirting? he came up to me randomly with a big smile and was like "come on, rach, get it together (he nicknamed me from rachel)" like teasing me playfully.

Was my coworker throwing out hints that he is single/interested?
