• Performed data modelling (ER) to identify key attributes (primary keys) for
carrier provisioning database, identified secondary keys to streamline data
access and foreign keys to establish associations between tables.
• Enhanced the UCS SmallTalk and JAVA servers to be compliant with HTTP
protocol version 1.1 which enabled the servers to communicate with different Web
Servers.
• Modified a simple lightweight, user friendly XML command line interface.

registered in Visigenic Java “Smart Agent Service” and Orbix SmallTalk Naming
Service. The application was registered to startup as a service in the windows
environment.
• Designed and Coded a JAVA/Swing application to manage VOIP Callp server
configurations.
• Contructed use cases for a complex web callp test scenarios for a Callp
application which included, two-way call handling, three-way call handling, call
waiting, message waiting and VOIP callp. The testcases verfied the VOIP callp
features and the JAVA window/dialog behavior/features. Testcases formulated from
the usecases were key to improving the product robustness.
• Played a key role in gigabit ethernet application requirements collection and
architecture design. Mentored team members on new platform by providing
assistance and training. Brought diverse teams together to achieve the project
milestones. Project completed 6 weeks ahead.
