Build an AI Intent Router with FastAPI, Prompt Engineering & Docker | Multi-Persona AI System

Description

In this video, I demonstrate how to build an AI Intent Router Service that intelligently routes user requests to specialized AI personas. This project uses prompt engineering, intent classification, and routing architecture to deliver accurate responses instead of relying on a single large prompt. The system first classifies the user’s intent and then routes the request to an expert persona such as Code Expert, Data Analyst, Writing Coach, or Career Advisor. The project also includes structured JSON outputs, logging, error handling, Docker containerization, and a FastAPI backend.
