About

As a software development manager at Amazon Web Services (AWS), I lead global engineering (35+ member teams with 3 engineering managers) teams focusing on scalable connectivity, availability, and authentication solutions for Redshift Serverless compute, a fully managed data warehouse service. With over nine years at AWS, my work has driven cost optimization strategies, including migrating services to Graviton, saving ~30% annually. Partnering with product teams, we developed a multi-year roadmap to address Serverless adoption blockers, enabling sustained revenue growth. In 2024–2025, my team developed instance type strategies and delivered key projects that removed major adoption blockers for Redshift Serverless, driving an estimated $20 million increase in revenue for 2025. My expertise encompasses architecting robust cloud services, designing multi-AZ solutions for 99.99% availability, and delivering critical multi-tenant connectivity service serving over 300 million daily connection requests for Redshift's Serverless and provisioned offerings. Passionate about simplifying large-scale distributed systems, I empower teams to innovate and deliver impactful solutions that integrate seamlessly with AWS analytics services, supporting millions of daily database connections across global regions.
