Sep 2006 – Till Date

Sr. J2EE Developer

Project: ITRAC

Primary aim of ITRAC is to manage the ‘IT Purchase’ process. ITRAC enables the user to select items from a predefined catalog, move it to a shopping cart and then check out. The system also provides the user with search facility, ability to store previous searches, and view history of purchases. The approval part of the system takes care of three levels of approval: the technical, management and financial approval. The system is expected to allow for flexibility to add additional approvers where needed by the user and also allow parallel approval for the three streams to expedite the workflow. A goal of ITRAC is to reduce the intense manual processing of these transactions. This project will automate and streamline many of the manual tasks in addition to others which cannot be enhanced further using the existing infrastructure/technology. The application is designed with improved order processing, ability to catalog items more thoroughly with additional interfacing to automate updates to both the Purchasing and Asset Management (Repository) applications

Project: Warranty Information System (WIS) and Early Warranty Tracking (EWT)

Warranty Information System is developed to track the Vehicle warranty activities. This system generates different kinds of metrics – condition per 100 vehicles sold (C/100), expense per unit sold (EPUS) and Cost per conditions (Cost/Cond).
