Trading Card Collection Manager
Full-stack web application for managing trading card collections with multi-user authentication. Built to learn user authentication, data isolation, and Supabase integration.
Architecture
Full-stack application with React frontend, FastAPI backend, and Supabase for authentication and PostgreSQL database. Row Level Security policies ensure proper data isolation between users.
React Frontend → FastAPI Backend → Supabase Auth → PostgreSQL → Row Level SecurityKey Features
Authentication System
Multi-user authentication with Supabase Auth, JWT token management, and secure session handling for user access control.
Data Isolation
Built Row Level Security (RLS) policies restricting users to their own card collections while maintaining system-wide admin capabilities.
Admin CLI
Created admin CLI for system management with full access to all user data, statistics, and batch operations.
Responsive UI
Designed responsive React frontend with Shadcn UI components, Tailwind CSS styling, and mobile-first design principles.
Technical Details
Supabase Integration
Integrated Supabase for PostgreSQL database, authentication, and Row Level Security policies with connection pooling and error handling.
FastAPI Backend
Built RESTful API with FastAPI including card CRUD operations, search functionality, favorites system, and user statistics endpoints.
Type Safety
Leveraged TypeScript for frontend and Pydantic models for backend ensuring type safety across the full-stack application.
