I’m Zhen Junwei, an AI Agent Development Engineer based in Guangzhou, China. I hold a Bachelor’s degree in Vehicle Engineering from South China University of Technology, and I’m a certified Senior AI Trainer (DAMO Academy). I have independently built two LLM applications from zero to production, covering deployment and evaluation. My flagship projects include: (1) an Enterprise Knowledge Base Agent using LangGraph, ChromaDB, and hybrid retrieval (Vector + BM25 + RRF + Rerank), which reduced hallucination rate from 33% to 0% through rigorous benchmarking and semantic caching; and (2) a BioDynamics Agent—a biomedical signal-pathway simulation system with a 22-node Supervisor-Worker architecture that eliminates code-generation hallucinations via deterministic template-based generation, achieving zero parameter violations and 43/43 traceable literature citations across five evaluation iterations. My tech stack spans Python, TypeScript, FastAPI, asyncio, Docker, Kubernetes, and CI/CD, with deep expertise in Prompt Engineering, Function Calling, MCP, and Agent orchestration. Previously, I worked in engineering roles at Tokyo Precision, improving product yield from 92% to 98%, and gained solid experience in simulation software development and automotive project management. I’m passionate about building reliable, measurable AI systems where every conclusion is auditable. Thank you!
