After 13 years of software development, I strongly believe in modular architecture and well-defined components. To realize this belief, I have been developing an open source family of projects with as its core. It is a full-stack integration of well-known frameworks (Hibernate, Spring and Wicket) and a container of “business-level component”, called “DModule”. Another area that I am so interested is data analysis and mining, and I have approached it both scientifically and technically. In the banking domain, I have developed data warehouse and BI projects, and proposed a target marketing solution via data mining. My current project in this area is DModule, which is an open source SQL-based application for reporting and data analysis. ©
