Senior🎓
Top SchoolJunjie Li is a Senior Product Manager based in Shanghai with 10 years of experience building developer tooling and AI-driven experiences at Microsoft, Trip.com, Apple, and ByteDance. He combines a strong technical foundation (MS in Computer Science from Northwestern) with hands-on engineering experience—contributing to high-profile open-source infrastructure like Microsoft’s Multiverso parameter server as a back-end developer and test automation engineer. At Microsoft he has driven developer experiences for Microsoft 365 Copilots, Declarative Agents, and developer toolkits for Teams, and now leads the Microsoft AI Toolkit. Junjie is fluent at translating low-level engineering tradeoffs into product direction, having worked on buffer/quantization internals and scalable web services early in his career. Colleagues rely on him to bridge product strategy and implementation, shipping practical tools like Adaptive Card Previewer and Teams App Test Tool. He’s equally comfortable in code, tests, and strategy, which helps him accelerate complex integrations between platform, developer experience, and AI capabilities.
