PROFESSIONAL EXPERIENCE

Responsibilities:

• Responsible for design, development, and release coordination of the application using J2EE architecture, in accordance with the Enterprise Architecture standards for interactive applications.
• Hands on working experience with IBM RSA 7.0 for developing, deploying and testing applications.
• Implemented multithreaded and robust application which can handle heavy and critical load of transactions ranging from 80 million to 120 million in a day.
• Implemented application using WebSphere MQ Messaging, MDB, DataGrid implementation for mobile based backend solution for Verizon Wireless.
• Responsible for middleware development using EJB / Session beans / MDB and MQ series that involves heavy load transactions like activation, de-activation, adding new features, removing features, downloading application, family plans, other plans, features, handset, MEID, ESN to update Oracle and IBM Extreme Scale DataGrid.
• IBM Extreme Scale DataGrid will be updated with each customer object that contains all information. Grid is in memory storage, so it provides very quick access rather than database.
