Hello, my name is

Zi Kai Chen

// 8+ years of solid experience


Who am I?

At 10 years old, I wrote my first "Hello World!" and loved programming ever since! I have published apps for Android, iPhone, Windows Phone, including one with over 2 million downloads.

Last winter, I interned at Facebook in Menlo Park, CA, where I worked on several core features in the video processing pipeline. Previously, I worked at Bloomberg on news and document search infrastructure in both the London and New York offices.

I love challenging myself, reading, travelling, clean design & typography, and most of all building great products.
