Resume/C.V.

I'm a strong programmer and good service provider. Most clients are satisfied with my service.

I'm quite good at Java programming and building web applications with Spring, JPA, various MVC frameworks, HTML & JQuery and GWT. Over 8 years experience and have good touch with new techs and best practices. Your ultimate problem solver.

I have adequate experience as main programmer, architect and team lead. I start my career as a developer in a company that provided Online Charging System, Business & Operation Support System, CRM to China Mobile, and soon became one of the main programmers of its ALM system. I learnt many good practices of software engineering such as CMMI (while in big team) and Agile (while in small team). Later I work as architect and then team lead in a small internet company. I can also train average programmers into much better ones.
