Word for person interested in latest technology programming-wise

I can't think of a noun right away, but there are quite a few adjectives: curious, inquisitive, studious.

And then there's always early adopter, but that has a slightly different meaning.

Wiktionary’s geek would be a perfect fit, if you don't mind the negative implication some see in the word:

A person intensely interested in a particular field or hobby, generally at the expense of broader social interaction. Often used with an attributive noun.

The closest word I can think of to suit your definition would be enthusiast. An enthusiast, though, is not necessarily interested in learning new aspects.

'Early Adopter' perhaps? Or an 'Evangelist'?

I once heard someone called a 'State of the Art-ist'!

Edit: not a noun, but might they also be described as 'always on the bleeding edge'?

"bleeding edge specialist" springs to mind, though it's not exactly elegant or simple.

Maybe "Technologically Adaptive"...?

The answer I hear the most in my workplace is cutting-edge.

at the latest or most advanced stage of development; innovative or pioneering.
