Is this guy clearly flirting?

I had an afterwork lately with other young people from my company. There was a guy that seemed interested asked me questions and next came to sit next to me. He also asked me what I wanted to drink and brought it to me.
Then I noticed he was laying his feet on the low part of my chair.
I felt something between us…

A bit later I wanted to show him something on my phone and several times he scrolled down on my screen while touching my fingers gently…2 or 3 times.
Is it a clear sign he is interested and want more?

I noticed he was a bit shy after that :)
