I have nearly 9 years of relationship database systems development and maintenance experience.In past years,i wrote a large number of complex business logic,including procedures,functions,triggers,and any script tools that needed for accomplishing working target. I often use c,c++,java,ruby,lua,perl,python,vbscript programming languages for importing,exporting,analyzing,processing business data.Microsoft Excel is my main tool used for representing result data,so i am familiar using office suite's macro. I also wrote some tools used for networking communications,parsing xml documents,simulating web browsers,encoding or decoding data etc.Most of them scratching by script languages. Stay motivated,sustained progressis,and harvest surprise! It's my life motto.
