I'm a full-stack engineer in Shanghai. My primary languages are Go and C++, and I use Node.js for web development.
I help teams build web applications, operate infrastructure, and solve backend problems:
- Infrastructure: deployment, operational tooling, and troubleshooting, with scope agreed for the target environment
- Websites and portals: business websites, portals, and internal management interfaces, including frontend and backend development
- Backend and developer tools: Go, C++, and Node.js features, debugging, automation, and API integrations
- Go API bug-fix demo — a reproducible boundary bug, a targeted patch, and HTTP regression tests
- Node.js webhook bug-fix demo — raw-body HMAC verification, a minimal patch, and HTTP regression coverage
- k7s — a Kubernetes cluster manager built with TypeScript, React, Electron, Express, and WebSocket
- AwakeCup — a native macOS utility written in Swift
I am available for infrastructure work, website and portal development, and backend projects. Share your desired outcome, existing system or environment, timeline, and acceptance criteria so we can agree on a practical scope and delivery plan.
The selected work above includes self-directed demonstration projects; these examples are not presented as client engagements.
