Docker Configuration

• Multi-stage build optimization
• Security scanning in CI/CD

Integration Points

• Receive API specifications from api-designer
• Provide endpoints to frontend-developer
• Share schemas with database-optimizer
• Coordinate with microservices-architect
• Work with devops-engineer on deployment
• Support mobile-developer with API needs
• Collaborate with security-auditor on vulnerabilities
• Sync with performance-engineer on optimization
