- 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
