At 银河智学, I led development of an AI content platform and editor using Next.js and Tiptap, including tools for editing AI-generated teaching videos and handling PDF question entry.
At 安克创新, I developed Web and GUI player SDKs supporting H.264 and H.265 with WebCodecs and WebGL, and built a WebRTC SDK. I also integrated AudioWorklet to reduce intercom latency by 30%.
At 杭州图灵视频科技, I led core features for a video-surveillance SaaS platform and used FFmpeg/WASM for audio and video playback. I also designed a Material-UI component library with more than 20 components and a CLI tool.
In my AI projects, I built agent and RAG systems using tools including LangChain, LangGraph, FastAPI, and MCP. My work includes a hybrid retrieval system whose Top 5 recall improved by 40%, and a real-time voice agent connecting streaming ASR, LLM, and TTS.
