Java / AI application engineer. Nine years shipping production systems end to end — now doing it with AI agents in the loop.
I build the unglamorous parts that have to actually work: video-surveillance and IoT backends, payment integrations, and the tooling that lets agents operate them safely.
📄 Case studies — how two production deliveries were actually built, with the constraints and the numbers.
| Area | Concrete experience |
|---|---|
| Video & IoT platforms | GB28181 / GA-T 1400 / RTSP integration with ZLMediaKit, H.264/H.265 playback with seek over HTTP Range, GA-T 1400 image and structured-data ingestion, MQTT (QoS 1, persistent sessions, topic-level permissions), RFID device onboarding |
| Payments & WeChat | Full WeChat Pay V3 loop (JSAPI payment → async callback → refund → refund callback), Alipay QR payment, WeChat Mini Programs, WeCom order management |
| AI-assisted delivery | MCP servers, agent skills, Claude Code workflows, read-only data-access patterns, prompt and context engineering |
| Platform & ops | Spring Boot services, MySQL / Redis, Kafka / RocketMQ, Docker deployment with backup and rollback validation, documentation and source handover |
mysql-ops-mcp — a read-only-first MCP server that gives an AI agent safe access to a private MySQL database through its own SSH tunnel. 24 unit tests, mutating tools unregistered by default, and a SQL guard that accepts nothing but a single read statement.
agent-skills — the rule sets I give my coding agents, extracted from real deliveries and sanitised: payment integration traps, deployment failure modes, database-change safety, campaign hot-configuration.
