FastAPI Backend Service

Overview

This project is a modern backend service built with FastAPI, focusing on async API design, clean architecture, and production-oriented concerns.

Key Features

• Async FastAPI endpoints
• JWT authentication
• Dependency-based rate limiting with Redis
• Clean separation of concerns
• Environment-based configuration
• Dockerized setup

Design Decisions

• FastAPI chosen for async support and dependency injection
• Redis used for rate limiting and external state
• JWT kept stateless for horizontal scaling

Future Improvements

• Background task processing
• Observability (metrics, tracing)
• Advanced caching strategies
