At Visa, I lead settlement engineering for payment gateways processing thousands of transactions per second across 400+ acquiring banks. I built self-service certification and RAG-based onboarding tools that reduced delivery time to under 48 hours and onboarding from three months to 15 days.
Previously at Lowe's, I designed an event-driven Kafka, Spark, Hadoop, and Trino platform across 1,500+ stores, contributing to a 70% sales improvement and 50% fewer customer complaints. I also modernized tax APIs to handle 1,000 TPS and improved throughput by 90%.
Across Visa, Lowe's, SAP Labs, NAGRA, and Wipro, I've built Java and Spring-based backend systems, led teams of up to 10 engineers, and raised engineering quality through design reviews, observability, automation, and secure delivery practices.
