Tim Roten engineered infrastructure and security enhancements for the CMSgov/beneficiary-fhir-data repository, focusing on automation, governance, and reliability. He modernized deployment workflows and standardized IAM access controls using Terraform, improving resource governance and reducing permission drift. Tim integrated Snyk for automated container image vulnerability scanning in AWS ECR, and implemented CloudTamer-driven QuickSight user provisioning to streamline BI access management. He modularized Terraform infrastructure, migrated backups to AWS Backup, and established GuardDuty health monitoring with Slack alerts. Working primarily with Python, Terraform, and AWS services, Tim delivered maintainable, scalable solutions that strengthened security posture and operational efficiency across the project.
