Hello there!

I am a developer. Welcome to my domain.

About Me


Hi. My name is Han. I am a data engineer, a full-stack developer, and a futurist. I studied Computer Science and Political Economics at University of California, Berkeley.

Currently, I am a Ruby on Rails developer and Data Miner at WalmartLabs working on Product Recommendation and gifts.walmart.com.

I've a senior programmer at a major nonprofit, a software engineer at a cloud company, the co-founder of an advertising platform, a researcher at Lawrence Berkeley Laboratory, a consultant for TubeMogul, and much more.

My large scale projects include creating Walmart Gifts from scratch. Designing and implementing the Berkeley Campus Wireless Network System, an enterprise-grade advertising delivery system, couple of e-commerce sites, and a search engine.

When I am not playing tennis or rock climbing, I am running Rails, pushing C++, hacking Python, commanding Android, or poking at Hive.

I am always up to meet new people. Feel free to shoot me an email!
