Is my building’s maintenance guy actually flirting with me?

I [27F] have neighbor who is also the maintenance guy for the building. He's in 30s, He’s talkative and he forgot his "screwdriver" in my apt x2 times, both times I texted him to pick it up. When he came over for the 3rd time, He joked "if I had his screwdriver" since he lost it again, and I said no. I usually expect maintenance guys to text me during business hours, but He also started to texting me at 9pm saying things like, "Hey You have a package in the mailroom" etc

Not sure about him?
