Currently a software engineer at Morgan Stanley Shanghai working on build system.

Goal: Software Architect
Domain: Compiler -> build system -> meta build system -> SDLC system (more on c++ on linux)
Part-time: OpenCV + Android App + Web App

I like to call myself a C++ programmer, although I also work with various "languages":

• I use C++ to write distributed, high performance program
• I use Java & JavaScript to build web/android applications
• I use Lua to design DSL
• I use Perl to process files and texts
• I use bash/batch to configure OS environments
• I use xml/json/yaml etc to design configuration format
• I use dot to draw diagrams
• I use English to work in an international environment :)

I believe a good programmer's core competence are:

• System internal
• Analyze & Design
• Algorithm
