System Overview & Architecture
A production-grade task management system engineered to demonstrate modern full-stack web architecture. Featuring JWT-based multi-user authentication, granular task prioritization, real-time status updates, and relational database persistence. The architecture cleanly separates an optimized Next.js frontend from a fast, asynchronous FastAPI REST API backend.
Technical Challenges Addressed
- •Achieving seamless cross-origin communication and session management between independent frontend and backend deployments.
- •Optimizing database query performance for concurrent user task filters.
Engineering Solutions & Implementation
- •Implemented strict CORS policies, token rotation, and typed API response contracts.
- •Designed clean relational schemas with indexed query parameters and optimistic UI updates on the Next.js client.
