Hi, I'm Lei.

I'm a Master's student studying Computer Science at Washington University in St. Louis. I love programming and implementing cool ideas. As a big fan of rock music, I love R.E.M., Radiohead and other great bands. I also read classic literature and take part in long distance running in my spare time.

Projects

Here are some selected projects I worked in past few years.

CodeMate

CodeMate is a real-time code sharing tool. It is designed for working on coding problems together. On the top-left panel, you can write code with nice syntax highlighting and auto complementation. On the bottom-left panel, you can get the output and check if your code works correctly in the console. The top-right panel is the place you paste your problem, and the bottom-right one is where you and your codemates communicate. This project uses node.js server with socket.io library to achieve high performance, and embeds ACE editor on the front side. Take a try on CodeMate.

Translation of Lightweight Django

Lightweight Django is a great book discussing using Django framework in a lightweight way written by Julia Elman and Mark Lavin, published by O'Reilly. The book mainly talks on how to make the most of Django’s decoupled design by choosing the components you need to build the lightweight applications you want. It also shows experienced Django developers how to include REST APIs, WebSockets, and client-side MVC frameworks such as Backbone.js into new or existing projects. I was very honored to be chosen by China Electric Power Press to be the authorized translator of this book, and has the opportunity to introduce the great ideas and approaches covered in this book to Chinese readers. The Chinese translation of this book will be published soon.
