FastAPI CRUD API from Scratch — Part 1: In-Memory (No Database)

In this video, we build a complete CRUD REST API using FastAPI from scratch — no database, no ORM, just pure FastAPI to understand the core concepts first.

This is Part 1 of the FastAPI Series where we start simple and progressively build toward a production-ready API.
