Johnson & Johnson, VA (September 2010-December 2011)

Java Developer

Project: Sales Supply Generation 2.0/2.4

The system enabled sales reps to order items through an internal website without the hassle of calling home office or using the intractable Siebel system to place orders. This system served approx 4000 reps (across 20-25 selling divisions/franchises) and 50 home office users ordering 3000 items. There were several business rules implemented within the system that determine the visibility, max order quantity, and inventory of each item vis-à-vis each sales rep. These business rules form the bulk of functionality within the system. This system interfaced with SAP system, which read orders submitted from the MSS and performs necessary validations and processes the orders. The SAP system passed on the order info to warehouse systems, which in turn performed the available inventory adjustment and shipment of the order. The warehouse system then fed the information back to MSS and SAP systems to let them sync up.
