I build AI agents and assistants into real products — grounded in your data, able to take actions safely, and tested before your users see them — along with the full-stack app around them.

What I can do for you
• AI agents and assistants — assistants that answer from your documents and data and show their sources, tool-calling agents and workflows that act through your API with guardrails, streaming chat interfaces, and MCP servers so Claude, ChatGPT or Cursor can work with your product.
• AI-powered MVPs, end to end — database schema and API design through the front end, tests, CI and deployment, so you work with one person instead of a relay of specialists. React / Next.js and TypeScript on the front; Node.js, Python, Go or Java / Spring Boot behind it; PostgreSQL, Redis, auth, payments and cloud hosting.
• Take-overs and fixes — apps another developer or an AI coding tool (Cursor, Lovable, Bolt, v0) left half-working: security gaps, crashes, broken streaming, missing tests.

Why work with me
• At Huawei I work on AI agent engineering, including our agent harness — the layer that runs the agent loop, manages context and controls which tools an agent may use. I have also built my own harness from scratch, with a web app that replays every step an agent takes.
• Built to hold up under real use. I design for the failures that cost money: double charges, oversold stock, duplicate orders, messages lost when a service goes down. My public projects prove it with tests — an ordering system that stays correct when many customers check out at once, and a Go microservice social network whose whole stack is started and tested end to end on every change.
• Every delivery comes with tests, an architecture diagram of the codebase, and a short written handoff. I work in English and Mandarin.
