Client – The Home Depot, Atlanta, GA
Role: Senior Java Developer January 2017 to May 2019
Project: Marketing Connection and Lago Integration
●Based on an IBM study done in 2011, there are several areas for improvement in the Merchandising/Marketing process. Various Advertising and Marketing groups reach out to Merchants for information to support upcoming events. Merchants do not have any tools to help with this submission or population of data. In addition, Merchants also spend time proofing multiple versions of print ads prior to production. Merchandising Transformation is focused on removing non-strategic tasks from the Merchant, and giving them time back to focus on Assortment Planning and other strategic areas.
●The Marketing Connection project will standardize and centralize the merchants interface with Advertising and Marketing merchandising submissions. This new tool will pre-populate data, allow for the re-use of previous submissions and streamline the submission process. This will optimize Merchant time spent on these tasks. By creating a tool that allows the Merchant to approve all data elements for an event we can free the Merchant from the process earlier than today and move downstream tasks to other teams. One key task being removed from the Merchant through this project is proofing of the various versions of print ads.

Furthermore, by rewriting the application with technology that is more robust and flexible, it will be easier for future teams to support and build on to.
The ability to view another Tool Rental Centers inventory systematically, as opposed to calling other centers helps to increase productivity of associates at all stores. An associate can view several stores inventory in the same amount of time it takes to call and get the inventory of one store. Along with increasing associates productivity, this also improves the shopping experience for the customer, resulting in repeat customers and increased revenue for Tool Rental.
