• Lead the design, implementation, testing, and deployment effort of a data-driven tax auditing system for the Chinese Tax Administration Office. • Interact with customers in both soliciting functional and service features and demonstrating system development progress. • Produce a highly scalable analytical core to identify possible tax evasion based on a combination of machine learning algorithms and statistical analyses using R and R.NET. • Create large scale ETL program to streamline tax filling information in preparation of data analysis. ETL program is implemented using Java and is designed to connect to both Oracle and MySQL databases. • Create convenient results display using JavaScript, jQuery, Bootstrap, eCharts, and other UI or graphic framework. • Design and test few distributed configurations to accommodate different sizes of subject data. Distributed configuration includes different nodes for ETL functions, data analysis core, results interpretation, and UI display; nodes may have different resources due to its data processing load. • Manage junior developers in achieving both the team goals of making quality software and their personal goals to gain necessary skills and work more comfortably in a team.

• Developed web-based applications using ASP.NET, MVC design pattern, Restful Web Services, and JavaScript (AJAX with jQuery). • Integrated applications with different legacy or new systems, including SharePoint programs, Crystal Report, SQL Server SSRS, and Oracle BI Scripts. • Responsible for design, implementation, and deployment of software applications.• Lead software development team in completing development assignment; activities include, but not limited to, daily scrum meeting, development planning, product design, programming/implementation, and testing. • Worked with customers in determining application specifications and demonstrating prototypes and final deliverables.

• Developed software development process components for the IBM Rational RUP/OpenUp Process Integration Tool.• Created components test scripts using Rational Method Composer. • Managed and maintained process components libraries and their matching test scripts; was able to develop convenience access database for these components and test scripts. • Developed and maintained commercial practices for the content libraries to present a business case of IBM Rational RUP/OpenUp and Rational Method Composer. • Worked remotely with development team which had team members from different locations across continental US.

Software Cost EstimationSoftware Engineering
