EXPERIENCE

                                                        Java/J2EE Developer,  Confidential

 

Project 1: FSET/ABAWD Policy Enhancements Project

Its purpose is to streamline and redesign the process by which workers manage FSET cases/individuals. It complies with federal FNS requirements by enhancing the CARES eligibility system. It eliminates the need for workers to use mainframe screens for FSET and ABAWD referrals. It reduces the training need for FSET workers to conduct the assessment and employability screening for FSET individuals. It improves the user experience and readily documents participant outcomes as a result of FSET program participation. Project involves creation of a tool, integrated with CWW, to support the administration of the FSET program.

 

  • Involved in the construction of Section: ‘Referral Management’ (3 pages out of 18)
  • Debug the existing application to gain overall understanding of the flow.
  • Involved in the design and end-to-end coding of New Pages: (1) Referral Search Criteria (2) Referral Search Results and (3) Referral Details.
  • Used JSP/Custom Tags for the front end development. Creation of Page IDs in CARES Studio

to register each new page and creation of element IDs (along with its html name and Label description) corresponding to each registered page.

  • Used JavaScript for client side validations
  • Using a Customized Struts like framework, pageactions were used to map front end data to EJBs (functions written in EJBs).
  • EJBs communicated with Business Objects (BO’s). Business Objects were used to write (1)  Logic for Server Side Validations (2) Logic for interacting with Database tables for data update and retrieval via dynamic/static/custom sql queries (either written in .xml files or DAOs).
  • Generated Java classes (Collection, Cargoes, DAO:  aided via the Architecture Team) for any new table created. ‘Cargo’ represents a row of the table and ‘Collection’ represents a list of Cargoes.
  • Wrote dynamic and static sql queries for data interchange to and from Database Tables. The persist method of the ‘Collection’ were also used for data interchange using the conventional sql methods of the DAO.
  • Wrote code to embed the functionality of a ‘Record Navigator’  in the ‘Referral Details’ page.
  • Aided in the merging of flows from different sources in driver flow.
  • Development and Integration of the Application using Eclipse IDE and used SubVersion as Version Control Tool. (for file synchronization, commit and resolving conflicts)
  • Built the applications and deployed them to WebSphere Server
  • Involved in the process of unit and integration testing.

 

Project 2: EPP Project

The purpose of this project is to Identify fraud and potential errors prior to confirming benefits in order to reduce incorrect eligibility determinations, QC errors and overpayments, Promote consistency and objectivity into the detection and management of fraud and potential errors across the state through automation and Mitigate impact on consortia and members through effective planning, decision making and communication

 

  • Involved in the construction of Section: ‘Address Management’
  • Involved in the design and end-to-end coding of New Pages: (1) Address Search Criteria (2) Address Search Results, and modifying Existing Pages:  (1) Search Criteria (2) General Case Information (3) Case Summary
  • Procedures similar to the above FSET/ABAWD Policy Enhancements Project adapted to code my section of the EPP project: but adhering to the new Project Requirements and Objectives which had the implementation of extra features. (such as using a combination of the USPostal Webservice call and writing code to implement the feature of ‘Address Verification’, implement the different criteria’s for Address Search match, implementation of a button functionality on the navigation panel (to appear once navigated to the Case Summary page and while within the content of the Case) to return to the Results page from anywhere within a ‘Case Context’ and other relevant features).
