At Target, I architect and scale the real-time data platform for Drive Up, Shipt, inventory availability, and fulfillment, supporting data flows across 2,000+ stores. I’ve established reusable streaming patterns and self-service platform capabilities for teams building production workloads.

At Airbnb, I led a Hadoop cluster modernization that grew managed data from 0.3PB to 11PB+ and helped deliver 2× faster query latency, 3× read throughput, and about 70% lower infrastructure costs. Earlier at Shopify, I built reporting pipelines and dashboards that replaced 10–15 hours a week of manual reporting.
