print("Hello, world.")

Hello, I'm Andy Liang.

I am a 22 year old undergraduate student at the University of Waterloo studying Computer Science. Professionally, I am an iOS developer and designer with many years of experience in Objective-C and Swift. Most recently, I worked at  Apple on the UIKit & SwiftUI team. Previously, I worked at Splunk> on the Splunk Mobile team, and at Yahoo! on the Flurry Analytics team.

On the side, I have worked on a handful of projects that can currently be found on the App Store, including: Sigma Planner and Blurry. Feel free to check out my GitHub for more open-source projects that I have created or contributed to.

Probably napping. 😴

Blurry is the go-to image blurring tool to help you apply beautiful blurs for your photos. It is perfect for creating wallpapers, backgrounds, and more.

With Blurry, you can customize and apply a blur effect on top of any photos from your photo library to create the perfect background for your wallpaper.

Through an extraordinarily simple UI, and a selection of dark blur, light blur, and custom colour blur, you can tweak the image effect however you like and save it when you are satisfied. It's that easy!
