PROJECT EXPERIENCE
TechXchange
This System is designed to setup a Contract Programmer Exchange to automate the process of hiring contract programmer through centralized Exchange. Members of the Exchange are Buyer and vendor of contract programmers. Buyer will submit their requirements to the Exchange and vendor will bid for the requirement. Exchange will help in selecting appropriate programmer.
This is a web based application using thin client three tiered architecture. Client side uses browser interface to interact with the business server and database server. Object Oriented technology is being used throughout the development cycle of the system that is being implementation using COM/DCOM and EJB in two different platforms. My responsibility is leading two groups technically to develop the product.

This application uses three-tier architecture in a Client / Server environment. The overall architecture of the Customer Care Platform model is so-called View-Subject-Controller framework. GUI objects are the View layer, which provide means to visualize the underlying business operation. These business objects and data represent the Subject layer capturing the business domain. Controller layer provides means to communicate with the external database sources.

Trigger Generation Tool for SYBASE Application
The tool to generate triggers from Foreign key and Primary key relationship to enforce referential integrity or consistency among the logically related data in the different tables. In general triggers are manually written and maintained. Any changes in the database table would affect the triggers. This tool will help the user to maintain the database integrity without writing any code for the triggers. Complete tools consists of two parts, first one is automatic generation of triggers and second one is a loader to load the generated triggers into the respective databases. Generation of triggers was developed using C++ language and the Loader part was developed using DB-Library. This project is done for PEPSI COLA INTERNATIONAL, USA to maintain referential integrity in their worldwide databases.

Design and development of a tool called IWS for re-engineering the block mode terminal based user interface of on-line transaction processing applications running in TANDEM computer system. Design and development of an interface ( having both the graphical and functional components) to an on-line transaction processing production environment. Object Oriented technology is being used throughout the development cycle of the system that is being implementation using the C++ language in the OS/2 environment. The main idea is to separate out the presentation characteristics from the application logic. The purpose is that the application developer can develop their application logic without being bothered about the intrinsic complicacies of the windowing API calls and at the same time application users can easily customize the presentation characteristics through our own high level Template Definition Language.
