- Predictive Demand Forecasting: Built production-grade pipelines using Python, SQL, and BigQuery to forecast demand for millions of customers. I implemented advanced time-series models (Prophet, LSTM) that reduced planning cycles by 90% and scaled across 21+ categories. - Prescriptive Price & Promo Optimization: Developed automated ML workflows in Vertex AI to estimate promotional uplift and price elasticity. This system delivered a measurable ~15% unit lift by optimizing product availability and pricing strategies. - Customer Loyalty & Growth Analytics: Analyzed 1.2M+ customer records to diagnose declining purchase behaviors. By designing targeted promotional strategies and running rigorous A/B tests, I generated $0.5M in incremental sales within the first week of a pilot. - Automated BI Infrastructure: Modernized legacy workflows (Excel/SAS) into robust GCP-based ETL pipelines. I designed executive-facing dashboards in Power BI and Tableau that provided real-time visibility into KPIs, assortment risk, and execution readiness.
