Tax Troubled Data Restructuring Project

• Spearheaded the design and development of a Spring, EJB, MVC and Hibernate based system that earned high accolades from the business area and retired about 10 EUCs and reduced the time it took to do tax processing from 2 weeks to 4 days.
• Message Driven beans developed to generate parallel processing streams and each stream will process a different population of loans serving 1000 concurrent socket connections. The system uses JMS on Weblogic, which allows for loose coupling and horizontal scaling into multiple boxes.
• Designed a simplistic batching framework to bundle loans together into batches for distributing to various functions within TDR Tax. Implemented many reusable services for this project, Cash Flow generation service, NPV computation service, AFR Applicable Federal Rate service, Deminimus Test Service and Level Yield Service to name a few.
• Data Service Layer implemented using the Java Persistence API JPA framework leveraged with the Spring framework. JPA to manage the relational data by creating a lightweight Java class whose state is persisted to a table in the relational database

Rules MISMO Data Translation Project

• Rules MISMO project transforms Freddie Mac infrastructure to use industry standard data MISMO , robust business rules management services, and a simplified, more transparent contracting process, to increase efficiency and reduce cost
• Developed architecture and IT future state vision for the project. Lead an Oracle SOA implementation, which seeks to create enterprise wide services, retiring and decommissioning existing non-scalable legacy components.
• Initiative involves changes to 10 systems and integration testing of over 15 systems ranging from mainframe to J2EE technologies that would use the enterprise service.
• Developed a stateless enterprise service that supports both synchronous and asynchronous service requests. Request and response structures defined and controlled in XSD.
• Designed the XSD for recomp and decomposition functionality. Designed the request and response XMLs for various different types of requests.
• Worked with the infrastructure team to fine tune the system to meet the performance requirements.
• Implemented business process using BPEL
