Apple
Notable projects: iOS UI, Game Center, Face Time, Garage Band, iPod Nano UI, & Mac OS X for Retina displays.
Facetime & Camera
One of my all time favorite projects! Zooming, Autofocus and HDR imaging were some of the features added.
I also got a sneak peak of the iPhone 4 in person and was featured in some of the marketing collateral. Check it out!
