10+ years experience on software development (C++, Python, Java, .Net, and Web, GIS based projects), strong technical writing skills and powerful problem solving abilities. I believe that honest, responsibility, team cooperation are key factors to make a project / product success, so I focus on excellent performance and working results with my team. I ever worked for big global companies for more than 7 years, was a senior software engineer for IBM-SPSS company for about 5 years. During that period, I was in charge of SPSS-Programmablity development that include SPSS-Python Plugin, SPSS-R Plugin and SPSS-.Net Plugin. I hold a master degree on Computer Science and Technology, major in Parallel Computing, Artificial intelligence. I hold a Ph.D on Structure Geology, major in Numerical Simulation of Continental Dynamics. So my special interesting is on combine Computational Geometry, Computer Graphics, and Artificial intelligence to solve complex spatial and / or location related problems. Big data analysis (based on Numpy and SciPy) is a plus as well. Please contact me if there is any project I can help.
