Developed a Java web internet/intranet application called Beneficiary Offset National Demonstration (BOND). The purpose of this pilot was is to give incentives to beneficiaries who are receiving disability insurance from the Social security Administration (SSA), which will lead to increased earnings and employment to the beneficiary. The BOND architecture consisted of four tiers: Web Service (internet) is used to expose the services methods to external clients, Presentation, Service and Persistence are the remainder of the three tiers which are internal to the SSA. An external Web Service end-user interaction initiates a layered processing of requests and responses through each tier.· Usage of Struts to handle data requests and responses (MVC)· Used IBATIS to externalize SQL· Created BPQY DAO Bridge for the service layer· JBoss rules engine to externalize all the business rules· The use of Java Data Transfer Objects (DTO), a bean that would be used across the various layers for data transfer· Java resource bundles to encapsulate the text used for the front-end pages· Section 508 Compliance

Developed a Java web service which allowed clients to retrieve database records based off the exposed methods of the WSDL, the data returned was in XML. The XML data was generated by using a DAO persistence framework, this helped hide the persistence layer implementation details by allowing pluggable DAO components to be swapped in and out easily by wiring this information in an external xml file. The key to this framework was that the SQL was specified in an external property file.· Used WSDL to describe the various services that are available · Usage of design patterns such as: DAO, Façade, Abstract Factory· JDBC

Developed a web intranet application called Benefits Planning Query (BPQY). BPQY provides a snapshot of the beneficiary's benefits and work history as it is stored in SSA's electronic records. As the lead developer, I was involved in the design, implementation and testing of BPQY. BPQY architecture consisted of three tiers: Presentation, Service, and Persistence. Each end-user interaction initiates a layered processing of requests and responses through each tier.· Usage of Struts to handle data requests and responses (MVC)· Used IBATIS to externalize SQL· Created BPQY DAO Bridge for the service layer· Apache FOP to print cover letters and the benefits· The use of Java Data Transfer Objects (DTO), a bean that would be used across the various layers for data transfer· Java resource bundles to encapsulate the text used for the front-end pages· Section 508 Compliance
