| 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. |
