 | 162 | +### File Structure  | 
 | 163 | +```  | 
 | 164 | +├── client/          # React frontend application  | 
 | 165 | +├── server/          # Express.js backend API  | 
 | 166 | +├── shared/          # Shared TypeScript types and schemas  | 
 | 167 | +├── dist/            # Production build output  | 
 | 168 | +├── uploads/         # File upload storage  | 
 | 169 | +└── migrations/      # Database migration files  | 
 | 170 | +```  | 
 | 171 | + | 
 | 172 | +The application follows a monorepo structure with clear separation between frontend, backend, and shared code, making it easy to maintain and scale both components independently while sharing common types and utilities.  |
