June 2025 monthly summary focusing on business value and technical achievements across the modernisation platform repos. Delivered reliability improvements to the reusable Terraform plan CI/CD workflow and centralised AWS Config S3 bucket configuration for multi-region deployments. These efforts reduced downstream pipeline failures, standardized configuration across regions, and demonstrated solid Terraform/Terragrunt expertise and CI/CD craftsmanship.

April 2025 performance highlights focused on driving consistency, maintainability, and cross-project adoption of IaC automation. Key delivery: a reusable Terraform plan/apply workflow for CI/CD across projects in ministryofjustice/modernisation-platform-ami-builds, implemented as a centralized GitHub Actions workflow and refactored across existing workflows to consume it. This reduces duplication, speeds up pipelines, and improves reliability of Terraform executions. Supporting work included updating documentation to reflect usage and onboarding guidance. Commit traceability is preserved across changes (see included commit references). Major bugs fixed: none reported this month. Overall impact: standardizes IaC operations across projects, lowers maintenance burden, accelerates onboarding of new projects, and provides a solid foundation for governance and auditability. Technologies/skills demonstrated: Terraform, GitHub Actions, reusable workflow design, YAML automation, cross-repo refactoring, and documentation.

January 2025 monthly summary for ministryofjustice/aws-root-account: Focused on stabilizing Security Hub findings workflow and aligning with SECURITY_CONTROL. Delivered a manual workaround to enable consolidated Security Hub findings and updated the control_finding_generator to SECURITY_CONTROL, ensuring consistent findings across environments. This addresses the gap where Terraform lacked direct support for this configuration and reduces manual drift in security findings.

December 2024 focused on stabilizing and extending the Instance Scheduler for production parity across environments. Delivered a critical bug fix by expanding the skip accounts list to include additional sandbox and development environments, accompanied by updates to integration tests and the template YAML to reflect the new skip list. These changes reduce the risk of unintended scheduling in non-production environments and improve deployment reliability. Impact: More predictable scheduling behavior in sandbox/dev, better alignment between code, tests, and templates, and reduced manual intervention during environment onboarding.

This month focused on delivering automated security monitoring and CI/CD enablement across two repositories, aligning Terraform baselines and AWS root account configurations to support secure, scalable operations. Implemented Security Hub alerting enablement with conditional provisioning and tightened findings filtering to CRITICAL, with Terratest-friendly infrastructure. Enabled Sprinkler CI/CD deployments by updating ModernisationPlatformSSOAdministrator role to include Sprinkler GitHub Actions access, supporting automated deployments and cross-account workflows. These changes improve proactive security visibility and accelerate deployment pipelines while reducing manual configuration. Technologies used include Terraform, AWS Security Hub, EventBridge, SNS, KMS, Terraform conditional provisioning, Terratest readiness, and IAM role updates.
