Application Architect

The original concept behind the Enterprise Notifications Architecture ENA to establish a standardized approach for systems to communicate to customers prior to the Enterprise Notifications Architecture, each application and business group maintained a separate subscription list and communicated to customers through a manual process. In Addition to handling the technical details of integration and delivery, each department was responsible for absorbing the time and postage expenses involved in their customer communications. The Enterprise Notifications Architecture is designed to provide subscription and notification capabilities to human end-points. The interface is designed to be generic and easily integrated into many applications. Mainframe Applications and J2EE Applications send Notification to ENA Application in the form of XML Data, ENA will convert those XML messages to Persistence Object using Castor Mapping Tool and process to End Point Multiple message endpoints through a single interface, Multi channel asynchronous interfaces, Client message priority, Subscription management, Message scheduling, Content Transform, Message Acknowledgment and Escalation, Error handling and Notification, Delivery status reporting and Message Retrieval.

Responsibilities:

• Responsible for Analyzing, designing, developing, coordinating and deploying web based application.
• Understanding the functional requirements and prepared a detailed Use Cases and Functional Requirement Documents from the Business Requirements Specifications.
• Responsible for User Interaction, Demonstration of the module for each iteration cycle.
• Responsible for analyzing and understanding of existing modules.
• Design and developed Delivery Failure Module to handle failure notifications.
• Worked on Receiving, Process and Deliver Modules.
• Developed Message Driven Bean MDB components for Receiving, Process and Deliver Modules.
• Followed OO technology and used re-usable components developed as a part of the main web application.
• Implemented object/relational persistence Hibernate for the domain model.
