• Maintain services once they are live by measuring and monitoring availability, latency and overall system health.
• Support the application CI/CD pipeline for promoting software into higher environments through validation and operational gating, and lead Mastercard in DevOps automation and best practices.
• Take a holistic approach to problem solving, by connecting the dots during a production event through the various technology stack that makes up the platform, to optimize mean time to recover.
