Are these signs that she's flirting with me?

This girl will try to catch my eye contact when we're talking and when I finally make eye contact it's like a laser beam like she's locked on and won't let go of my eye contact. and when I say something nice or compliment her she will giggle and look away, for example I hadn't seen her in a while and when she came up to talk to me I said "it's good to have you back around here" and she giggled/nervously laughed and looked away for a second. she also asks questions like how I've been and what I've been up to but I thought maybe she might just be being friendly.

but is that flirting and what other signs should I look for. thank you
