Available to hire
I’m Xuhong Yan, an AI engineer focused on building agentic workflows and tooling to automate end-to-end review, testing, documentation, and release processes. I design and implement coding-assistant style tools, retrieval-backed systems, evaluation checks, and production software integrations.
I have strong experience across Python/FastAPI, TypeScript/Next.js, GitHub Actions, Docker, Neo4j, ChromaDB, and CI/CD; I specialize in reliable automation and observable systems. I thrive in engineering-agent roles that require robust orchestration, prompt testing, and secure state management across frontend and backend services.
