Python AI System Design: FastAPI, RAG & MCPs

Description

Building a basic AI chatbot is easy. Building a robust, production-ready backend to power it is where the real engineering happens. In this video, we architect a complete AI backend from scratch using FastAPI and the OpenAI SDK. We go beyond the basics and break down the core system design concepts every modern AI engineer needs to know: structuring your APIs, integrating MCPs (Model Context Protocol), mastering Function Calling, and wiring up a RAG (Retrieval-Augmented Generation) pipeline. If you are looking to level up your AI system design and build scalable applications, this is your blueprint.
