Demystify AI agents by building them yourself. Local LLMs, no black boxes, real understanding of function calling, memory, and ReAct patterns.

Demystify RAG by building it from scratch. Local LLMs, no black boxes - real understanding of embeddings, vector search, retrieval, and context-augmented generation.

Build AI agents from first principles using a local LLM - no frameworks, no cloud APIs, no hidden reasoning.

Production-grade RAG on Azure with Node.js - covers Bicep IaC, event-driven ingestion, LangGraph agents, CosmosDB memory, hybrid vector search, Managed Identity security, and full observability. The next step after rag-from-scratch.

Real-world patterns for shipping AI agents to production. Learn versioning, cost optimization, multi-tenancy, guardrails, and observability through runnable TypeScript examples.
