+- **Processing Performance**: Response time monitoring
+
+### Log Analysis
+
+```bash
+# Check application logs
+tail -f logs/app.log
+
+# Monitor processing stats
+curl http://localhost:5000/api/summary | jq '.data'
+```
+
+## 🔧 Troubleshooting
+
+### Common Issues
+
+1. **Low Acceptance Rate**
+   - Check if validation rules are too strict
+   - Review mobile photo quality expectations
+   - Adjust thresholds in `config.py`
+
+2. **Performance Issues**
+   - Monitor memory usage for large images
+   - Consider image resizing for very large uploads
+   - Check model loading performance
+
+3. **Deployment Issues**
+   - Verify all dependencies installed
+   - Check file permissions for storage directories
+   - Ensure models are downloaded correctly
+
+### Support
+
+For issues and improvements:
+1. Check logs in `logs/` directory
+2. Test individual validation components
+3. Review configuration in `config.py`
+4. Use API testing tools for debugging
+
+## 📈 Performance Optimization
+
+### Current Optimizations
+
+- **Mobile-Friendly Rules**: Relaxed thresholds for mobile photography
+- **Weighted Scoring**: Intelligent partial credit system
+- **Efficient Processing**: Optimized validation pipeline
+- **Smart Caching**: Model loading optimization
+
+### Future Enhancements
+
+- [ ] Real-time processing optimization
+- [ ] Advanced object detection integration
+- [ ] GPS metadata validation
+- [ ] Batch processing capabilities
+- [ ] API rate limiting
+- [ ] Enhanced mobile UI

+ufw allow 443    # HTTPS
+ufw deny 5000    # Block development port
+ufw enable
+```
+
+---
+
+## 🚨 Troubleshooting
+
+### **Common Issues & Solutions**
+
+#### **1. Low Acceptance Rate**
+```bash
+# Check current rates
+curl http://localhost:8000/api/summary
+
+# Solution: Validation rules already optimized for mobile photos
+# Current acceptance rate: 35-40%
+# If still too low, adjust thresholds in config.py
+```
+
+#### **2. Performance Issues**
+```bash
+# Check processing time
+time curl -X POST -F 'image=@test.jpg' http://localhost:8000/api/validate
+
+# Solutions:
+# - Increase worker count
+# - Add more CPU/memory
+# - Optimize image preprocessing
+```
+
+#### **3. Memory Issues**
+```bash
+# Monitor memory usage
+free -h
+ps aux | grep gunicorn
+
+# Solutions:
+# - Reduce max file size
+# - Implement image resizing
+# - Restart workers periodically
+```
+
+#### **4. File Storage Issues**
+```bash
+# Check disk space
+df -h
+
+# Clean up old files
+find storage/temp -type f -mtime +1 -delete
+find storage/rejected -type f -mtime +7 -delete
+```
+
+---
+
+## 📈 Scaling & Optimization
+
+### **Horizontal Scaling**
+
+```bash
+# Multiple server instances
+docker run -d --name civic-quality-1 -p 8001:8000 civic-quality-app:v2.0
+docker run -d --name civic-quality-2 -p 8002:8000 civic-quality-app:v2.0
+
+# Load balancer configuration
+# Route traffic across multiple instances
+```
+
+### **Performance Optimization**
+
+```python
+# config.py optimizations
+VALIDATION_RULES = {
+    # Already optimized for mobile photography
+    # Higher thresholds = lower acceptance but better quality
+    # Lower thresholds = higher acceptance but more false positives
+}
+```
+
+### **Future Enhancements**
+
+- [ ] **Redis Caching**: Cache validation results
+- [ ] **Background Processing**: Async image processing
+- [ ] **CDN Integration**: Faster image delivery
+- [ ] **Auto-scaling**: Dynamic worker adjustment

+
+## Production Considerations
+
+### Security
+
+1. **HTTPS**: Always use HTTPS in production
+2. **Secret Key**: Use a strong, random secret key
+3. **File Validation**: All uploads are validated for type and size
+4. **CORS**: Configure CORS appropriately for your domain
+
+### Performance
+
+1. **Gunicorn**: Production WSGI server with multiple workers
+2. **Model Caching**: YOLO model loaded once and cached
+3. **File Cleanup**: Temporary files automatically cleaned up
+4. **Optimized Processing**: Parallel processing for multiple validations
+
+### Monitoring
+
+1. **Health Check**: `/api/health` endpoint for load balancer
+2. **Metrics**: Processing time and validation statistics
+3. **Logging**: Structured logging for debugging
+4. **Storage Monitoring**: Track processed/rejected ratios
+
+### Scaling
+
+1. **Horizontal**: Multiple container instances
+2. **Load Balancer**: Distribute requests across instances
+3. **Storage**: Use cloud storage for uploaded files
+4. **Database**: Optional database for audit logs
+
+## API Endpoints
+
+- `GET /api/mobile` - Mobile upload interface
+- `POST /api/upload` - Image upload and analysis
+- `GET /api/health` - Health check
+- `GET /api/summary` - Processing statistics
+
+## Testing Production Deployment
+
+```bash
+# Test health endpoint
+curl http://localhost:8000/api/health
+
+# Test image upload (mobile interface)
+open http://localhost:8000/api/mobile
+
+# Test API directly
+curl -X POST \
+  -F "image=@test_image.jpg" \
+  http://localhost:8000/api/upload
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Model download fails**: Check internet connectivity
+2. **Large file uploads**: Increase `MAX_CONTENT_LENGTH`
+3. **Permission errors**: Check file permissions on storage directories
+4. **Memory issues**: Increase container memory allocation
+
+### Logs

+curl http://your-domain:8000/api/summary
+```
+
+---
+
+### **Option 2: Manual Production Server**
+
+#### **Server Setup:**
+```bash
+# 1. Install production dependencies
+pip install -r requirements.txt gunicorn
+
+# 2. Setup directories
+python scripts/setup_directories.py
+python scripts/download_models.py
+
+# 3. Configure environment
+export SECRET_KEY="your-production-secret-key"
+export FLASK_ENV="production"
+export MAX_CONTENT_LENGTH="33554432"
+```
+
+#### **Start Production Server:**
+```bash
+# Using Gunicorn (recommended)
+gunicorn --bind 0.0.0.0:8000 \
+  --workers 4 \
+  --timeout 120 \
+  --max-requests 1000 \
+  production:app
+
+# Or use provided script
+chmod +x start_production.sh
+./start_production.sh
+```
+
+---
+
+## 📊 Post-Deployment Testing
+
+### **✅ Comprehensive API Testing**
+
+```bash
+# Run full test suite
+python api_test.py
+
+# Expected results:
+# - 5/5 tests passed
+# - All endpoints responding correctly
+# - Acceptance rate: 35-40%
+# - Processing time: <2 seconds
+```
+
+### **✅ Load Testing (Optional)**
+
+```bash
+# Simple load test
+ab -n 100 -c 10 http://your-domain:8000/api/health
+
+# Image validation load test
+for i in {1..10}; do
+  curl -X POST -F 'image=@test_image.jpg' \
+       http://your-domain:8000/api/validate &
+done
+wait
+```
+
+### **✅ Mobile Interface Testing**
+
+1. **Access mobile interface**: `http://your-domain:8000/mobile_upload.html`
+2. **Test camera capture**: Use device camera to take photo
+3. **Test file upload**: Upload existing photo from gallery
+4. **Verify validation**: Check response format and scoring
+5. **Test various scenarios**: Different lighting, angles, quality
+
+---
+
+## 🔒 Security Hardening
+
+### **✅ Production Security Checklist**
+
+- [x] **Environment Variables**: All secrets externalized
+- [x] **HTTPS**: SSL/TLS certificate configured (recommended)
+- [x] **File Validation**: Strict image format checking implemented
+- [x] **Size Limits**: 32MB maximum enforced
+- [x] **Input Sanitization**: All uploads validated and sanitized
+- [x] **Temporary Cleanup**: Auto-cleanup mechanisms in place
+- [x] **Error Handling**: No sensitive information in error responses
+
+### **✅ Firewall Configuration**
+
+```bash
+# Recommended firewall rules
+ufw allow 22     # SSH access
+ufw allow 80     # HTTP
+ufw allow 443    # HTTPS  
+ufw allow 8000   # API port (or use nginx proxy)
+ufw deny 5000    # Block development port
+ufw enable
+```
+
+---
+
+## 📈 Monitoring & Maintenance
+
+### **✅ Key Metrics to Track**
+
+1. **Application Health**
+   ```bash
+   curl http://your-domain:8000/api/health
+   # Should return: "status": "healthy"
+   ```
+
+2. **Processing Statistics**
+   ```bash
+   curl http://your-domain:8000/api/summary
+   # Monitor acceptance rate (target: 35-40%)
+   ```
+
+3. **Response Times**
+   ```bash
+   time curl -X POST -F 'image=@test.jpg' \
+        http://your-domain:8000/api/validate
+   # Target: <2 seconds
+   ```
+
+4. **System Resources**
+   ```bash
+   htop           # CPU and memory usage
+   df -h          # Disk space
+   du -sh storage/  # Storage usage
+   ```
+
+### **✅ Log Monitoring**
+
+```bash
+# Application logs
+tail -f logs/app.log
+
+# Docker logs (if using Docker)
+docker-compose logs -f civic-quality-app
+
+# System logs
+journalctl -u civic-quality-app -f
+```
+
+### **✅ Maintenance Tasks**
+
+#### **Daily:**
+- [ ] Check application health endpoint
+- [ ] Monitor acceptance rates
+- [ ] Review error logs
+
+#### **Weekly:**
+- [ ] Clean up old temporary files
+- [ ] Review processing statistics
+- [ ] Check disk space usage
+- [ ] Monitor performance metrics
+
+#### **Monthly:**
+- [ ] Review and optimize validation rules if needed
+- [ ] Update dependencies (test first)
+- [ ] Backup configuration and logs
+- [ ] Performance optimization review
+
+---
+
+## 🚨 Troubleshooting Guide
+
+### **Common Issues & Quick Fixes**
+
+#### **1. API Not Responding**
+```bash
+# Check if service is running
+curl http://localhost:8000/api/health
+
+# Restart if needed
+docker-compose restart civic-quality-app
+# OR
+pkill -f gunicorn && ./start_production.sh
+```
+
+#### **2. Low Acceptance Rate**
+```bash
+# Check current rate
+curl http://localhost:8000/api/summary
+
+# Current optimization: 35-40% acceptance rate
+# Rules already optimized for mobile photography
+# No action needed unless specific requirements change
+```
+
+#### **3. Slow Processing**
+```bash
+# Check response time
+time curl -X POST -F 'image=@test.jpg' \
+     http://localhost:8000/api/validate
+
+# If >3 seconds:
+# - Check CPU usage (htop)
+# - Consider increasing workers
+# - Check available memory
+```
+
+#### **4. Storage Issues**
+```bash
+# Check disk space
+df -h
+
+# Clean old files
+find storage/temp -type f -mtime +1 -delete
+find storage/rejected -type f -mtime +7 -delete
+```
+
+---
