About This Course
Comprehensive curriculum analysis and educational value proposition from the official provider library hubs.
- The Model Context Protocol (MCP): Be one of the first to master this standard. You will build Custom MCP Servers in Node.js to connect your AI to real-world data (like Weather APIs) and expose them as tools to Claude, Gemini, or OpenAI.
- Advanced RAG Pipelines: Move beyond basics. We implement Vector Search using ChromaDB and pgVector, handling embeddings, chunking, and ingestion manually to give you total control.
- Native Tool Calling: Learn how to make LLMs (Gemini & OpenAI) strictly structured JSON to trigger functions in your code—the backbone of Agentic AI.
- Math & Theory: We don't just import libraries. We cover the logic behind Cosine Similarity, Vector spaces, and Retrieval scoring so you understand why your retrieval works.
- Frontend: React (Latest), TailwindCSS, Vite
- Backend: Node.js, Express, TypeScript
- AI Models: Google Gemini, OpenAI GPT Models
- Vector Databases: ChromaDB, pgVector (PostgreSQL)
- Protocols: MCP (Model Context Protocol)
