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 Bloomberg in London UK, where I designed and implemented a feature complete A/B testing platorm in under 4 months time. I also had the opportunity to travel around Ireland, Amsterdam, Paris, Italy, and Barcelona, and met some really amazing people!

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