Data Scientist at Amazon who invented Skippy, a supply chain planning system used across Europe and North America.

United States
Message

At Amazon, I invented Skippy, a financial and planning intelligence system for inventory management, and helped scale it across Europe and North America, covering 250+ warehouses. It combines optimization, financial cost logic, ETL pipelines, and a user interface; corporate records estimate it delivered $100M–$1B in annualized savings.

As a Data Scientist II, I owned and extended Skippy for North America and Europe. I improved bottleneck-detection accuracy by more than 50% versus manual planning and developed disruption and scenario-planning capabilities to re-optimize network flows under constraints.

I’ve also built production-grade AWS applications and integrated hierarchical optimization into large-scale planning solutions. My work connects mathematical modeling and data systems with the supply chain and corporate finance decisions they support.
