About Yisheng Jiang

I build high-performance JavaScript applications, with a focus on React-based interactive UIs, real-time systems, and browser-native media pipelines. I’ve built complex graphical tools like a topology editor (React + SVG with WASM and Graphviz) and AI-assisted search experiences via an MCP server, and I’m comfortable owning the full loop from data models and API contracts through responsive UI, state management, and performance tuning. A standout project is my WASM MIDI SoundFont Player: a React + Vite app engineered for tight timing and low-latency playback, where MIDI parsing, tempo handling, and event scheduling run in a dedicated worker that streams note events to per-track AudioWorklet synth processors via transferred message ports, keeping audio deterministic even under heavy UI load. I also built a React-based video editor using FFmpeg and an xAI (Grok) chat assistant to drive editing actions, demonstrating end-to-end product work while staying anchored in JavaScript and modern web architecture.
