Top SchoolJimmy Tsang is a software engineer with nine years of experience building infrastructure, security, and AI operations tooling across large-scale consumer platforms. A UC Berkeley EECS graduate now based in San Francisco, he has shipped cross-system integrations, CICD optimizations that halved deployment time, and cloud migrations at Yahoo/Verizon Media before moving into AI Ops at TikTok/ByteDance. He blends product-minded engineering—having built user-facing React/React Native interfaces and backend services in Go—with a practical security focus, contributing to projects like Athenz for x.509-based service authentication. Jimmy’s background spans startups to hyperscale companies, and he brings a knack for automating maintenance and operational workflows that keep complex systems reliable and fast. Notably, his early work at Tesla and Cartrack demonstrates an ability to move from prototype UI/UX to production-grade services and data-driven improvements.
