Ai Engineer Expert

This is a solid production AI engineering reference that covers the full stack from LLM integration to RAG systems. You get working examples of unified clients with fallback handling, vector database implementations using Chroma and LangChain, and practical prompt engineering patterns like chain-of-thought and few-shot learning. The code is production-focused with proper error handling, streaming responses, and function calling. Most valuable when you're moving beyond proof-of-concept work and need to build reliable AI systems that handle failures gracefully and scale properly. The agent system section appears incomplete but the RAG and LLM client implementations are comprehensive enough to fork and modify for real projects.
