Client: Target

Project: Target.com Promotion Application Phase II

Role: ATG/Java Developer

This project is an enhancement version of existing Target.com Promotion Application with few modules as, Clearance Pricing Automation, Competitive Pricing and TPA-I enhancements. Clearance Pricing Automation: - The current clearance price management system which involves manual activities and semi-automated clearance process would be redeveloped into new TPA-II which is based on Oracle, ATG Framework with the minimal manual interventions and automated clearance schedule. TPA-II online application will have the look and feel similar to that of the existing TPA-I application.
