• 🤖 AI Agents: Long-horizon autonomous agents — context engineering, agent harness design, Agent Skills, multi-agent orchestration, MCP, tool-use & sandboxed execution, and RAG over long docs.
• 🖥️ Full-Stack: End-to-end product delivery — API design (REST/GraphQL), authentication & authorization, async backends, modern frontends (React/Next.js/Vue), CI/CD pipelines, and cloud deployment.
• 🌐 Distributed Systems: Scalable architectures — service decomposition, message queues (Kafka/RabbitMQ), event-driven workflows, distributed caching, consistency & fault tolerance, and cloud-native microservices on Kubernetes.

I build and maintain open-source AI Agent projects. Some of my work:

Project	Description	Stars
ethanhq/cc-fleet	Run third-party LLMs (DeepSeek, GLM, Qwen, etc.) as native Claude Code teammates or one-shot subagents — a Go CLI plus Claude Code skill
