About This Guide

In the previous guide, Building a RAG System from Scratch with pgvector and Gemini, we implemented a RAG system from scratch using pgvector and Gemini, then extended it through Tool Use, AI Agents, MCP, and cloud deployment.

This guide is the sequel. It takes you from "building a system that works" to "making a system that works in production".
