Senior Application Developer

• The Overpayment Tracking is a web application that provides user interfaces and business logic to business users helping them to log and track overpayments on claims.
• Overpayments are logged on Claim IDs. Admins or vendors can log an overpayment and track it to recovery. Vendors can log a list of overpayments at once by uploading a file.
• Identified overpayment amounts are recovered and recoveries are allocated for the respective claims.
• Thus the overpayments are tracked until they are completely recovered and closed.

Responsibilities

• Worked on adding new functionality to the OPT application in the SSN Masking Session Handling
• Changed all the OPT Web Screens to display only the last four digits of SSN for security reasons and provided a button to unmask them when needed.
• Unmasking will be tracked in a downstream system, the Audit API, which is a centralized logging for the unmask activity.
• Created SSN Object in Java as an object oriented approach to capture SSN data as it is retrieved and this object contains support for masked, unmasked and encrypted version of SSN.
• Created custom JSP tags for screens to generate the HTML and these tags also helps in building the data for auditing. Worked with Servlet at the request processing end.
• When an unmask button is clicked, an AJAX call is made and Spring MVC Controller processes the request and returns back the unmasked value as JSON object. Thus the JSON object is decoded and the SSN value on the page is updated without reloading the entire page.
• Transactions happen through the encrypted version of the object and the required business data is recorded for the Audit API call.
• Used Aetna Internal Framework AEFW when developing Java Code.
• Using Javascript, session time is set/reset and the application is redirected to a timeout page once session times out. This is done with the help of cookies.
• Session timeout was handled across multiple windows as well like dialog windows, modal dialogs and tabbed windows.
• Developed various JUnit test cases for Unit and Functional Testing respectively.
• Was part of Windows 7 upgradation where few components on IE 6 were not compatible in IE8.
• Used Clearcase for version control. RAD is the IDE and WebSphere is the server used. Used Clear Quest to update and track the defect status.
