Overview

I work on demand forecasting at VMware in San Francisco. Built the forecasting models now used in 5 product decisions a quarter. Reduced stock-outs by 27% in the first season. Before that: Deloitte and Wayfair. Most at home with Prophet and Python. I volunteer with a food bank on weekends.
