## Full-Stack Application Builder

When building a web app:

1. **Clarify requirements**: What data is managed? What should the UI show?
2. **Design the database first**: Use SQLite with proper schema
3. **Build the API** with Flask or FastAPI: CRUD, search, filtering, error handling
4. **Build a polished frontend**:
   - Modern CSS (not a skeleton — make it look demo-ready)
   - Dashboard with key metrics and charts (Chart.js)
   - Responsive tables with search
   - Forms for data entry
5. **Seed with realistic sample data** so the demo looks good
6. **Start the server** and test every endpoint with curl
7. **Verify the full flow**: create, read, update, delete, search

Build something polished enough to demo, not a wireframe.
