Joshua Zhu

Hi there, welcome to my homepage :-)

Just a quick word for those curious about me. I'm Joshua Zhu, a software developer who is particularly interested in how to write high performance servers. I work for Taobao, the largest e-commerce website in Asia. Currently, I live with my wife and lovely baby daughter in Hangzhou, China.

Blog & Twitter

I note down my thoughts, opinions randomly on my blog (, Twitter (@zhuzhaoyuan) and Weibo (@淘叔度). Maybe you could find some fun stuff there.
