Implemented multiple projects

Project 1:
ManageSparesCapability
The aim of this project was to develop a Java based JPEG2000 Decoder for a Japanese Client. This is an extension of the JPEG2000 encoder project. The decoder was designed to decode 60 HD frames per second. The project provided a mechanism for the NetOps team to quickly identify and track the status of any spares order and if appropriate, relate it back to the trouble ticket that spawned the order. The functionality of creation of Spares and Returns Orders was owned by systems within the Enterprise Management Platform (EMP).

Responsibilities:

• Understanding the business requirement and detailed design specification.
• Developing JSF and JSP pages for creating a WEB-PORTAL
• Writing PL\\SQL stored procedure and trigger for interacting with Databases.

Project 2:
BT Fleet
The project provided a mechanism for the EMP PAL which gave the facility to load the electronic files containing invoice data through a UI screen. System validated the data based on the defined rules using BPEL and ODI. For valid records, Maintenance Request, Purchase Order, Supplier Invoice, and Customer Recharge, etc. was created. For invalid records, the error details were presented to the user through UI screen. The user had the ability to correct certain errors and re-submit the data for processing. It reduced level of manual effort in re-keying information into Willow from the AA Breakdown file.

Responsibilities

• Analysis of project requirement.

Project 5:
EnvironmentReportAutomation,DashboardforserverandDatabasestatus.
The project customized some of the pages of the application by identifying and changing some of the java classes to reflect the required customization and to trace other classes, which may get affected due to the changes made. Once these classes were identified, similar classes were made & original classes were replaced with them, and then the stability of the system was tested.
