Tom Ogle enhanced the CircleCI IAM policy within the ministryofjustice/modernisation-platform repository, focusing on the digital-prison-reporting environment. He implemented targeted permissions using Terraform and HCL, enabling ECR tag listing and S3 bucket notification management to streamline deployment and operational workflows. By aligning access controls with least-privilege principles, Tom reduced manual intervention and improved the security posture of CI/CD processes. His work consolidated policy changes under a single initiative, supporting end-to-end deployment improvements. The technical depth of the changes demonstrated a strong understanding of AWS IAM and cloud engineering, addressing both operational efficiency and security requirements in a production environment.
