Summary
🤩
RockstarLing Chen is a software engineer based in Sunnyvale with six years of experience building backend and security-focused systems at Google and Uber. A Carnegie Mellon Robotics graduate, Ling began in SLAM and 3D mapping before transitioning to scalable backend fare systems and now cloud-native security work. At Google and in Istio open-source projects they focused on authentication, authorization, and audit logging, adding performance tests and integration tests that improved security regression coverage. Past work at Uber includes leading dynamic fares features and regulatory surcharge implementations that protected market access and revenue. Comfortable across research-grade robotics algorithms and production backend engineering, Ling brings a rare combination of robotics rigor and security-minded cloud engineering. Outside core roles they’ve contributed measurable test and monitoring improvements to the widely used Istio service mesh.
