About Me

My photo
You Xu ( Zach )
I am a software engineer specializing in Java EE application development. I created this blog site so that I can put my notes here and refer back to them if I forget the details. I have a PhD degree in Mathematics and a MS degree in Computer Science. In spare time, I like to play tennis and ping-pong, run, garden, and do other outdoor activities. I like to watch Discovery Channel. The Planet Earth show is one of my favorites. I created an ERP application which is an order management system. My web site https://www.lakexy.com has more information of it.
