ninja barista 

An espresso machine operator with not only exceptional skill in producing the finest espresso shots and espresso-based drinks, but also with extreme dexterity, zen-like demeanor and lightning quick speed behind the bar. Generally is quiet and modest, but can deliver a killer shot of espresso.

Compare and contrast with the rockstar barista.

Before I even put down my two dollars, that ninja barista had a killer doubleshot of espresso in front of me.
