At AWS EC2, I led a high-performing engineering team focused on OS imaging and system management technologies. In May 2021, we launched the Cross Cloud Competitive Benchmarking Service, enabling benchmarking across AWS, Azure, GCP, and AliCloud. At re:Invent 2020, we introduced the Systems Manager Fleet Manager Service for remote server management, and in 2019, we unveiled AWS Task Orchestrator and Executor (AWSTOE), a key part of EC2 Image Builder. From 2018 to 2021, my team also qualified Windows and Linux OS for upcoming EC2 instance types.
