• Optimize API response times and database performance
• Implement global CDN delivery for heavy 3D assets
• Build rate limiting, throttling, and backpressure mechanisms
• Optimize storage and retrieval of large 3D files
• Profile and improve CPU, memory, and network performance

5. Infrastructure & DevOps

• Architect AWS infrastructure (EC2, S3, Lambda, RDS, ElastiCache)
• Build CI/CD pipelines for automated deployments and rollbacks
• Use Infrastructure-as-Code tools (Terraform, CloudFormation)
• Set up monitoring, logging, and alerting systems
• Use Docker and Kubernetes for container orchestration
• Implement security best practices for data, networks, and secrets
• Define disaster recovery and business continuity plans

6. Integration & APIs
