Hi Everyone: My name is Ruoyun Jing, I am an undergraduate student in Northwest University(China) of Software Engineering.Although i am a girl,i really love coding and algorithms!!! I've coded many algorithms problems with C++ and Python,and got Bronze Metal in ACMICPC Asia Shenyang Regional contest. GSoC is really a precious chance for me to get in touch with open source software. After reading all the organizatuions and their projects, I'm pretty interested in R-tree serialization and static map. Despite my lack of project experience,i will try my best to learn ,code and communicate with mentor!!! Looking forward from you.:) Thank -- Northwest University of China Software Engineering jingry0321@gmail.com <jingry0321@163.com>
