This coworker of mine... does he like me?

So I have this guy at work. We first spoke a few weeks ago when i thought i made a huge error at work and i asked everyone desperate for help. Je said calmly that i needed to work threw a huge list of actions in order to fix this. After that he went home. Lucky for me, the real fix was short. When i Saw him afterward in the parking lot i asked him why he would give me such advice. He grinned and said i shouldn't trust him that easily. The following days whenever i Saw him i would frown at him and he would be all smiles, winks, blowing kisses and teasing me from afar when he heard me deal with difficult work or when my very expressieve face made a question mark look or An angry one.

Last week he sat down next to me during the work shift which het started whith saying things like; im not gonna tease you too much to day etc. We kept joking and laughing the whole shift; i warmed up to him because he is really funny and witty. When i had a question and wanted to ask another coworker het rushes to my side to help me and if he couldnt find the fix he would drop his work to look for the fix. When i spoke about the time a Guy i once dated was my customer (we work at a callcenter) i had to say it twice that i was nog longer interested in this guy and he wanted to know the reason why i wasn't interested in him anymore.
We also have a saying here; you tease a girl to ask for a kiss. When i asked him; why do you keep teasing me he started to say; you know what they say tease a girl for..

Following days at work; i catch him staring a lot at me and when i notice this he gets a huge grinn and blows kisses or signs at me. Whenever i ask a trainer at work about a difficult an 'odd case i can either hear him chuckle slightly in the distance or him commenting.

He is a very easygoing/good talker type of guy but he seems to focus more on me at work with the staring and laughing etc. My question is; do you think he likes me and if yes how do i let him know i like him back?
