This project focuses on building a production-grade backend API, going beyond basic CRUD to support advanced filtering, performance monitoring, and real-world API constraints.
The system is built using FastAPI with a layered architecture (router → service → repository) and fully async database operations using SQLAlchemy. Authentication uses JWT with secure password hashing, while rate limiting is enforced per endpoint to protect critical routes.
The API supports complex filtering across multiple parameters (status, priority, category, date range, and search) using composable query construction, ensuring scalability without sacrificing maintainability.
A lightweight monitoring layer tracks request counts, latency, and slow requests, exposed via a /metrics endpoint—reinforcing observability as a core part of system design rather than an afterthought.
