• As the chief data architect and tech lead for the Enterprise DataBase (EDB) project of a P&C insurance project, provided data solutions for their enterprise OLTP system’s data repository that replaced legacy systems.• On the conceptual level, used the top-down design principles to simplify the overall EDB design, achieved superb flexibility and extensibility, and with greatly reduced system complexity, which resulted in shorter development and test cycles for both database backend and application frontend layers, hence reduced overall project development costs, and future maintenance costs as well.• Processed and analyzed requirements from SMEs; coordinated with other teams on designs and activity planning.• Designed and implemented enterprise data architecture, define data processes, and provide data solutions for normalized OLTP, while laying foundation for future dimensional OLAP.• Improved the design and performance of the backend database repository of the National Transit project for FTA (Federal Transit Administration), Department of Transportation. Also helped in implementation.• Defined & designed process & data flow, defined data quality standards, data models (conceptual, logical, physical, normalized, dimensional), created and built database.• Defined, designed and implemented specialized triggers (i.e., functionalities beyond RI); complex stored procedures,• Helped application developers on their queries and accessing data repository; performance tuning.• Helped in other projects as fire-fighter to resolve urgent and acute issues.

• Worked on system revision and redesign according to new requirements, and performance improvements, involved in interviewing SME, defining project scope, and problem discovery, driving problem formulation and solution process, for normalized OLTP & dimensional OLAP..• Defined new process and component solutions, and advised on their implementations.• Created conceptual, logical and physical data schemas, implemented databases and tuned performances. • Provided data solution and the database design for a logistic operator; designed their new logistic operation optimization model and solution.

Worked in partnership with Business and IT at a major global financial institution to build a consolidated Retail and Wholesale Analytical Portfolio data warehouse supporting Consumer Finance, Account, Customer Analytics, and Credit & Risk Analytics for Consumer and Business banking sectors. This enterprise system will enable analytical models for risk strategy setting including risk rating and quantification, cross-sell measurement, and portfolio management/execution functions and empower underwriting department to make approval decisions in their loan portfolio. Analyzed and managed financial data quality/cleansing processes in data integration work, performed mapping and ETL process tasks. Contributed to data model revision process. My work helped to lay a solid foundation for the successful completion of the project.

• Responsible for customer requirement assessment and analysis, architecture and component design, data analysis and modeling, database design and development. • Designed and developed a rule-based double-entry financial accounting journal system that allocates funds to all relevant parties and accounts according to the rules. Also designed and implemented analysis and reporting components for this financial system. • Conceptualization, data analysis and modeling, and architecutural design of a POS (Point of Sales) system.• Member of a team in conceptualization, data modeling, and design of a Labour Scheduling system.• Member of a team in the design and development of some healthcare organization web system.• Made contributions on various projects, including strategic planning and development.

• Responsible for the overall EBP system design. Developed the data model and the conceptual framework, including the specifications of the architecture and high-level requirement. • Led the design and development team.• Server database design and development. • Led the design and developement of some web-based applications. • Strategic planning and development.

• Worked on R&D of ServicePath, a telecom service providers’ real-time communication network service assessment, assurance and provision system. • Led the data repository team. Designed and implemented a real time VLDB (Very Large DataBase), solving many related technical issues in the process. Established data standardization across the enterprise.• Made many technical contributions to the architectural and functional design and processes, algorithm designs and implementations, and various components, using my analytical and problem solving skills. • Led company’s patent process, including patent evaluation, writing and filing. Personally wrote and filed five patent applications, of which three have been granted. My work had major impact on strengthening the company’s intellectual property position, and gained the company a competitive advantage.• Created interactive shell script to automate complete system install process at customer site, including DBMS installation and configuration, application installation and configuration, application database instance creation and configuration, based on customers' infrastructure system environment parameters.

• Undertook research and development of Libretto, a real-time communication network usage data collection and usage-based network billing system. In charge of backend data management related design and development.• Managed, designed and implemented the data solution for Libretto system. Performance tests and tuning.• Designed and implemented a prototype for Net Mediator, a key component of Libretto. Net Mediator analyses and aggregates raw data into a concentrated and refined form that is more palatable for network billing, services and various data analyses. • Analyzed network traffic data en massy in search of user usage and traffic patterns. This work directly resulted in significant improvement on the abstract data model and real-time network usage monitoring and billing structures.

• Designed and implemented the process flow and some of the interactive financial service call center systems and their underlying financial data model, database design, and application components.• Designed and implemented the Small Business Loan Application system overhaul.• Led the Y2K project that was delivered satisfactorily two week ahead of schedule.
