Hello, I am Andy Liang.

I am an iOS developer and designer, and a Computer Science student at the University of Waterloo. I currently work at  Apple as a UIKit Engineer. I was previously an iOS Engineering intern at Splunk> on its mobile team. Before that, I worked as a Software Engineering Intern at Yahoo on the Flurry SDK team.
