 ## Overview
 
-go4.video is a fully functional professional video streaming platform that integrates directly with Bunny.net CDN for secure video delivery. The application successfully streams 85 private videos from the user's Bunny.net library through a custom web interface. It features a YouTube-like design with video cards, search functionality, and a professional video player with comprehensive controls including central play button, progress bar, volume control, time display, and fullscreen capabilities.
+go4.video is a fully functional professional video streaming platform with a comprehensive backend infrastructure for video upload, editing, and management. The application features both Bunny.net CDN integration for existing content and a complete PostgreSQL-based system for new video uploads and user management. It includes a YouTube-like design with video cards, search functionality, and a professional video player with comprehensive controls including central play button, progress bar, volume control, time display, and fullscreen capabilities.

 The frontend uses a **component composition pattern** with separate components for video cards, search headers, video grids, and modal players. This approach promotes reusability and maintains clean separation of concerns.
 
 ### Backend Architecture
-The backend follows a **REST API pattern** using **Express.js**:
+The backend follows a **comprehensive REST API pattern** using **Express.js** with full CRUD operations:
 
 - **Server Framework**: Express.js with TypeScript for type-safe server development
-- **API Design**: RESTful endpoints for video operations (GET, POST) with pagination support
-- **Storage Layer**: Abstracted storage interface allowing for multiple implementations (currently using in-memory storage with plans for database integration)
-- **Middleware**: Custom logging middleware for API request tracking and error handling
+- **API Design**: Complete RESTful API with authentication, video management, upload tracking, categories, and tags
+- **Authentication**: Session-based authentication with bcrypt password hashing and user management
+- **Storage Layer**: Flexible abstracted storage interface with PostgreSQL database, Bunny.net integration, and memory storage fallback
+- **Upload System**: Comprehensive video upload system with progress tracking, file handling via Multer, and metadata management
+- **Middleware**: Authentication middleware, session management, file upload handling, and error processing
+- **Database Integration**: Full PostgreSQL integration with Drizzle ORM and comprehensive schema management
 
-The server implements a **middleware pattern** for request processing and includes development-specific tooling like Vite integration for hot module replacement.
+The server implements a **layered architecture pattern** with storage abstraction, authentication middleware, and comprehensive video management capabilities.
 
 ### Data Storage Architecture
-The application uses a **flexible storage abstraction**:
+The application uses a **comprehensive multi-tier storage system**:
 
-- **ORM**: Drizzle ORM configured for PostgreSQL with type-safe database operations
-- **Database**: PostgreSQL (configured via Neon Database) for production data persistence
-- **Schema Management**: Centralized schema definitions in TypeScript with automatic type generation
-- **Development Storage**: In-memory storage implementation for development and testing
+- **Primary Storage**: PostgreSQL database with full schema including users, videos, video_uploads, categories, tags, and video_tags tables
+- **ORM**: Drizzle ORM configured for PostgreSQL with complete type-safe database operations and relationship management
+- **Database**: PostgreSQL (configured via environment variables) for production data persistence with automatic fallback
+- **Schema Management**: Comprehensive schema definitions in TypeScript with automatic type generation and validation
+- **Storage Abstraction**: Interface-based design supporting multiple storage backends (DatabaseStorage, BunnyStorage, MemStorage)
+- **File Storage**: Local file system for video uploads with configurable upload directory and file management
+- **CDN Integration**: Bunny.net CDN integration for existing video content with secure signed URL authentication
 
-The storage layer uses an **interface-based design** allowing easy switching between storage implementations without affecting business logic.
+The storage layer implements a **strategic fallback pattern**: PostgreSQL database first, Bunny.net integration second, memory storage as final fallback, ensuring reliability across different deployment scenarios.
 
 ### Authentication & Authorization
-Currently uses **session-based architecture**:
+Complete **session-based authentication system**:
 
-- **Session Management**: Express sessions with PostgreSQL session store (connect-pg-simple)
-- **Security**: CORS configuration and secure session handling
-- **Future-Ready**: Architecture prepared for JWT or OAuth integration
+- **User Management**: Full user registration, login, and profile management with bcrypt password hashing
+- **Session Management**: Express sessions with configurable session store and secure cookie handling
+- **Authentication Middleware**: Comprehensive authentication middleware protecting all sensitive routes
+- **Security**: CORS configuration, secure session handling, and password encryption with bcrypt (12 rounds)
+- **API Protection**: All video upload, editing, and management operations require authentication
+- **User Data**: User profiles with username, email, admin privileges, and profile management capabilities
 
 ### Build & Development Architecture
 The application uses a **monorepo structure** with shared code:
