Hi there 👋 I'm Jiang Zhenhua (Sam)

Senior iOS / Client-side Engineer · iOS dev since 2015 · Beijing

I build client-side products for live streaming, sports content, interaction and audio/video scenarios — driving complex features from prototyping to production. Solid iOS fundamentals with cross-platform reach (KMM/Compose, Cocos, Electron/Node.js, React Native, HarmonyOS ArkTS), strong in performance optimization and stability, and fluent with AI tooling across the dev workflow.
