Dave Arrowsmith engineered centralized and secure access controls for Athena within the ministryofjustice/cloud-platform-environments repository, focusing on robust IAM role management across multiple environments. He migrated hardcoded ARNs to AWS SSM Parameter Store, integrated dynamic secret propagation into Kubernetes, and refactored Terraform modules to source ARNs from SSM, reducing manual secret handling and improving governance. Dave also enhanced IAM role resolution for environment-specific access and addressed reliability issues in role fallback logic. Using Terraform, YAML, and AWS IAM, his work streamlined access provisioning, strengthened cloud security, and enabled safer, faster environment deployments, demonstrating depth in cloud infrastructure and configuration management.

May 2025 monthly summary focusing on key accomplishments and business value for ministryofjustice/cloud-platform-environments. Delivered centralized Athena role ARN management via AWS SSM parameters, refactored Terraform to source ARNs from SSM, and updated IAM policies, IRSA module, and Kubernetes secrets to align with the new model. Fixed a source-code metadata URL bug in namespace.yaml to ensure accurate repository attribution. These changes improve security (reduced secret exposure), governance consistency across prod/preprod/dev, and streamline access-control provisioning, enabling safer and faster environment provisioning across platforms. Technologies demonstrated include Terraform, AWS SSM Parameters, IAM, IRSA, Kubernetes secrets, and GitOps practices across multiple environments.

April 2025 monthly summary for ministryofjustice/cloud-platform-environments: Delivered centralized and secure Athena access through AWS SSM Parameter Store and Kubernetes secrets, consolidating IAM role ARNs and enabling dynamic secret updates across dev and preprod environments. Migrated away from hardcoded ARNs, moved ARNs into SSM, and wired them into Kubernetes secrets with dynamic updates; refined access patterns to storage and retrieval for SSM parameters. Implemented dynamic Kubernetes secret provisioning from SSM to minimize manual secret handling and deployments. Conducted a temporary workaround in test environments to restore Athena access by reintroducing hardcoded ARNs, ensuring testing continuity during the transition (commit f80d2c55c3db607bbbd5d5c6546d422a657e9588)."
