2015 Summer Intern
Aug 2016 - Oct 2020
Bentonville, AR
- Boosted online grocery sales by $160 million using Hive to develop an automated weekly audit report for 1 billion store-items that identifies discrepancies among ecommerce site back-end systems to fix items that are erroneously showing as out-of-stock, to provide root cause analysis for back-end system engineers, and to provide leadership with inventory accuracy KPI’s
- Orchestrated development of AI product that automatically assigns items to slots in a warehouse by gathering requirements from stakeholders, designing linear programming optimization model, preparing dataset via R/SQL/Altyerx, overseeing model improvements and CPLEX implementation, providing logistics leadership with project updates, and launching product in 5 warehouses with estimated $5 million in labor savings
- Enhanced demand forecasts by cleansing poor historical sales data for every item in all 4,000+ stores using R and Hadoop Hive to implement linear models that predict when a drop in sales is due to unfulfilled customer demand
