+docker-compose logs -f [service]     # Service logs
+curl http://localhost:8000/health    # Backend health
+curl http://localhost:8501           # Frontend health
+```
+
+## Implementation Priorities
+
+### **Phase 1: Environment Optimization** (Ongoing)
+1. **Docker Optimization**
+   ```dockerfile
+   # Optimize Dockerfile for faster builds
+   FROM python:3.11-slim
+   
+   # Install system dependencies
+   RUN apt-get update && apt-get install -y \
+       build-essential \
+       && rm -rf /var/lib/apt/lists/*
+   
+   # Copy requirements first for better caching
+   COPY requirements-backend.txt .
+   RUN pip install --no-cache-dir -r requirements-backend.txt
+   
+   # Copy application code
+   COPY src/ ./src/
+   ```
+
+2. **Health Check Enhancement**
+   ```yaml
+   # Improved health checks
+   backend:
+     healthcheck:
+       test: ["CMD", "curl", "-f", "http://localhost:8000/health"]
+       interval: 30s
+       timeout: 10s
+       retries: 3
+       start_period: 40s
+   ```
+
+3. **Development Volume Optimization**
+   ```yaml
+   # Optimize development volumes
+   backend:
+     volumes:
+       - ./src:/app/src:cached  # Cached for better performance
+       - backend_cache:/app/.cache  # Cache pip packages
+   ```
+
+### **Phase 2: Integration Testing** (Days 12-13)
+1. **Service Integration Tests**
+   ```python
+   # Integration test framework
+   class TestServiceIntegration:
+       async def test_database_connection(self):
+           """Test PostgreSQL connection and basic queries"""
+           
+       async def test_backend_api_endpoints(self):
+           """Test all backend API endpoints"""
+           
+       async def test_frontend_backend_communication(self):
+           """Test frontend can communicate with backend"""
+           
+       async def test_ai_service_integration(self):
+           """Test AI services integration"""
+   ```
+
+2. **End-to-End Workflow Tests**
+   ```python
+   # E2E test scenarios
+   class TestCompleteWorkflow:
+       async def test_user_registration_to_document_generation(self):
+           """Test complete user journey"""
+           # 1. User registration
+           # 2. Application creation  
+           # 3. AI processing phases
+           # 4. Document generation
+           # 5. Document editing
+   ```
+
+### **Phase 3: Performance Monitoring** (Day 14)
+1. **System Metrics Collection**
+   ```python
+   # Performance monitoring
+   class SystemMonitor:
+       def collect_container_metrics(self):
+           """Collect Docker container resource usage"""
+           
+       def monitor_api_response_times(self):
+           """Monitor backend API performance"""
+           
+       def track_database_performance(self):
+           """Track PostgreSQL query performance"""
+           
+       def monitor_ai_processing_times(self):
+           """Track AI service response times"""
+   ```
+
+2. **Automated Health Checks**
+   ```bash
+   # Health check script
+   #!/bin/bash
+   set -e
+   
+   echo "Checking service health..."
+   
+   # Check PostgreSQL
+   docker-compose exec postgres pg_isready -U jobforge_user
+   
+   # Check Backend API
+   curl -f http://localhost:8000/health
+   
+   # Check Frontend
+   curl -f http://localhost:8501
+   
+   echo "All services healthy!"
+   ```
+
+## Docker Management Best Practices
+
+### **Development Workflow Commands**
+```bash
+# Daily development commands
+docker-compose up -d                    # Start all services
+docker-compose logs -f backend          # Monitor backend logs
+docker-compose logs -f frontend         # Monitor frontend logs
+docker-compose restart backend          # Restart after code changes
+docker-compose down && docker-compose up -d  # Full restart
+
+# Debugging commands
+docker-compose ps                        # Check service status
+docker-compose exec backend bash        # Access backend container
+docker-compose exec postgres psql -U jobforge_user -d jobforge_mvp  # Database access
+
+# Cleanup commands
+docker-compose down -v                   # Stop and remove volumes
+docker system prune -f                  # Clean up Docker resources
+docker-compose build --no-cache         # Rebuild containers
+```
+
+### **Container Debugging Strategies**
+```bash
+# Service not starting
+docker-compose logs [service_name]      # Check startup logs
+docker-compose ps                       # Check exit codes
+docker-compose config                   # Validate compose syntax
+
+# Network issues
+docker network ls                       # List networks
+docker network inspect jobforge_default # Inspect network
+docker-compose exec backend ping postgres  # Test connectivity
+
+# Resource issues
+docker stats                            # Monitor resource usage
+docker system df                        # Check disk usage
+```
+
+## Quality Standards & Monitoring
+
+### **Service Reliability Requirements**
+- **Container Uptime**: >99.9% during development
+- **Health Check Success**: >95% success rate
+- **Service Start Time**: <60 seconds for full stack
+- **Build Time**: <5 minutes for complete rebuild
+
+### **Integration Testing Requirements**
+```bash
+# Integration test execution
+docker-compose -f docker-compose.test.yml up --build --abort-on-container-exit
+docker-compose -f docker-compose.test.yml down -v
+
+# Test coverage requirements
+# - Database connectivity: 100%
+# - API endpoint availability: 100%  
+# - Service communication: 100%
+# - Error handling: >90%
+```
+
+### **Performance Monitoring**
+```python
+# Performance tracking
+class InfrastructureMetrics:
+    def track_container_resource_usage(self):
+        """Monitor CPU, memory, disk usage per container"""
+        
+    def track_api_response_times(self):
+        """Monitor backend API performance"""
+        
+    def track_database_query_performance(self):
+        """Monitor PostgreSQL performance"""
+        
+    def generate_performance_report(self):
+        """Daily performance summary"""
+```
+
+## Troubleshooting Runbook
+
+### **Common Issues & Solutions**
+
+#### **Port Already in Use**
+```bash
+# Find process using port
+lsof -i :8501  # or :8000, :5432
+
+# Kill process
+kill -9 [PID]
+
+# Alternative: Change ports in docker-compose.yml
+```
+
+#### **Database Connection Issues**
+```bash
+# Check PostgreSQL status
+docker-compose ps postgres
+docker-compose logs postgres
+
+# Test database connection
+docker-compose exec postgres pg_isready -U jobforge_user
+
+# Reset database
+docker-compose down -v
+docker-compose up -d postgres
+```
+
+#### **Service Dependencies Not Working**
+```bash
+# Check health check status
+docker-compose ps
+
+# Restart with dependency order
+docker-compose down
+docker-compose up -d postgres
+# Wait for postgres to be healthy
+docker-compose up -d backend
+# Wait for backend to be healthy  
+docker-compose up -d frontend
+```
+
+#### **Memory/Resource Issues**
+```bash
+# Check container resource usage
+docker stats
+
+# Clean up Docker resources
+docker system prune -a -f
+docker volume prune -f
+
+# Increase Docker Desktop resources if needed
+```
+
+### **Emergency Recovery Procedures**
+```bash
+# Complete environment reset
+docker-compose down -v
+docker system prune -a -f
+docker-compose build --no-cache
+docker-compose up -d
+
+# Backup/restore database
+docker-compose exec postgres pg_dump -U jobforge_user jobforge_mvp > backup.sql
+docker-compose exec -T postgres psql -U jobforge_user jobforge_mvp < backup.sql
+```
+
+## Documentation Maintenance
+
+### **Infrastructure Documentation Updates**
+- Keep `docker-compose.yml` properly commented
+- Update `README.md` troubleshooting section with new issues
+- Maintain `GETTING_STARTED.md` with accurate setup steps
+- Document any infrastructure changes in git commits
+
+### **Monitoring and Alerting**
+```python
+# Infrastructure monitoring script
+def check_system_health():
+    """Comprehensive system health check"""
+    services = ['postgres', 'backend', 'frontend']
+    
+    for service in services:
+        health = check_service_health(service)
+        if not health:
+            alert_team(f"{service} is unhealthy")
+            
+def check_service_health(service: str) -> bool:
+    """Check individual service health"""
+    # Implementation specific to each service
+    pass
+```
+
+## Development Support
