Summary
🤩
RockstarAlexandra Lee is a Principal Engineer at AWS in Seattle, focused on API Gateway and API platform reliability with eight years of industry experience. She pairs cloud-scale systems work with an academic background in robotics and embedded systems—specializing in localization and computer vision—holding a BE from the University of Pennsylvania and an MS in Computer Science from Harvard. At AWS she has driven IoT and web performance initiatives, delivering measurable reductions in page load times and improving device integration at scale. An active open-source contributor to AWS's widely used s2n-tls, she implemented ECDSA signing/verification, refactored socket I/O into separate read/write contexts, and added custom I/O callbacks to increase flexibility and maintainability. This blend of low-level security and embedded-systems thinking with platform engineering lets her bridge device constraints and cloud API design to build robust, secure services.
