October 2025 monthly summary: Delivered major security, governance, and scalability improvements across Terraform baselines and AWS root-account management. Key features include a centralized SSM Public Sharing Settings module with lifecycle protections, and an upgrade of the Baselines module to v8.2.1 to integrate new security safeguards. Implemented Inspector2 auto-enrollment across EC2, ECR, and Lambda with regional support and delegated admin permissions, plus multi-account deployment workflow. Advanced admin/member account separation and chunking to manage 100+ accounts, including root account hardening and exclusion of the management account. Added collaborator for EM accounts and improved code quality with formatting cleanups, tests scaffolding, and dependency management. These efforts reduce risk, strengthen security governance, and enable scalable, repeatable deployments across multiple AWS accounts and regions.

September 2025 performance summary for the MOJ modernization platform portfolio. Delivered security hardening, CI/CD reliability improvements, and tightened access controls across development, testing, and multi-region production baselines. Resulted in lower deployment risk, improved compliance with GOV.UK notification and data access standards, and a clearer, more maintainable infrastructure configuration.

August 2025: Focused on securing and simplifying CircleCI integration within the ministryofjustice/modernisation-platform by shifting to per-project IAM roles, optimizing governance and policy management, and deprecating legacy CircleCI role configuration. Delivered project-level isolation for CircleCI IAM, governance-led policy reductions, policy cleanup for Identity Center actions, and the documentation/CI tooling updates to reflect changes. These efforts reduce AWS trust policy size constraints, decrease operational overhead, and improve security posture for new and existing projects, while aligning with security/compliance requirements.

July 2025 monthly summary for ministryofjustice/modernisation-platform focusing on business value and technical outcomes. Delivered stability and security enhancements across alerting, monitoring, and access controls, while provisioning a new environment to support scale. The work combined threshold tuning, alerting improvements, security hardening, and documentation/workflow fixes to improve reliability, incident response, and governance.

June 2025: Delivered targeted security, governance, and production-readiness improvements across ministryofjustice/modernisation-platform and its Terraform baselines. Implemented FIS access for sandbox and developer roles, tightened NACL SSH rules for LAA environments, added production environment variables for the property-cafm data migration, standardized tagging across providers/resources, and adjusted anomaly detection threshold to reduce false positives. In the Terraform baselines, added tagging to the AWS Security Hub module and the AWS Config SNS key to improve resource identification and cost allocation. These changes reduce security risk, accelerate production deployments, improve cost governance, and enhance alerting fidelity, demonstrating strong proficiency in IAM, network security, infrastructure as code, and AWS governance tooling.

May 2025 highlights: Implemented automated stale-branch pruning improvements across the modernization platform, fortified cross-repo access with AWS Secrets Manager, and refreshed incident response documentation and runbooks. Also removed an unused AWS Secrets Manager secret in the root account to reduce risk and clutter. These changes improve pruning reliability, security posture, and incident readiness, while reducing infrastructure complexity across two repositories.

April 2025 saw a set of high-impact automation and governance enhancements across MOJ platforms, delivering concrete business value through safer automation, reduced clutter, and strengthened security controls. Key features delivered included upgrading the AWS Nuke workflow in the environments repo to v3.51.1 with hardened CI/CD, dry-run and destructive-operation toggles, enhanced credentials handling, Nuke Apply, Lightsail force-delete, and Slack notifications. Stale-branch cleanup automation was implemented across MOJ repos with a safe dry-run option to minimize operational risk and repository clutter. An Identity and Access Management overhaul (Entra ID / AWS SSO) introduced group-based access, account assignments, and governance changes (removing outdated roles) with Platform Engineer role assignments to improve security and onboarding. A deprecation fix for Terraform AWS Chatbot IAM roles replaced the deprecated managed_policy_arns with aws_iam_role_policy_attachment to align with best practices. Documentation corrections and improvements were also completed to ensure accuracy and maintainability.

March 2025 performance highlights across the Modernisation Platform family focused on security hardening, infrastructure-as-code reliability, and CI/CD readiness. Delivered targeted access-control improvements, clarifications in resource declarations, and test hygiene enhancements that reduce risk and accelerate safe deployments.

February 2025 performance summary: Delivered key infra decommissioning, security hardening, and governance improvements across the Modernisation Platform portfolio. Decommissioned delius-nextcloud environment; enabled S3 GuardDuty malware protection; enforced collaborator policy by removing inactive collaborators; updated access levels documentation; and enhanced GitHub Actions OIDC integration for automated malware protection workflows. These efforts reduced unnecessary surface area, strengthened security controls, and improved ongoing maintenance and compliance.

January 2025 performance summary for ministryofjustice/modernisation-platform. Delivered environment-aware IAM/Instance Scheduler Role Provisioning to limit role creation to non-production member accounts, reducing blast radius and aligning with environment-specific IAM policies. Refactored Terraform configuration to separate backend into backend.tf, modularize provider config, and updated ADR to reflect additional workspaces (pagerduty, single-sign-on, environments). Updated documentation to maintain currency. These changes improve security posture, reduce operational risk, and enhance maintainability for multi-environment deployments.

December 2024 monthly summary for ministryofjustice/modernisation-platform. Focused on delivering business value through improved operational readiness, clearer documentation, and automated access-management for on-call operations. Key work centered on enhancing S3 bucket management documentation and runbooks, and implementing PagerDuty onboarding and user provisioning via Terraform to ensure reliable alert routing and on-call coverage.

November 2024 performance summary: Delivered security and reliability improvements across key platforms, strengthening threat detection for S3, improving key management, and stabilizing CI/CD workflows to support ongoing development. Key outcomes include implementing GuardDuty S3 malware protection with a new role and policy, adding an S3 malware implementation guide, switching environment management to a multi-region KMS key, addressing GuardDuty integration issues and condition checks, and stabilising CI pipelines by temporarily disabling code formatting steps in GitHub Actions.

October 2024 monthly summary focusing on formatting standardization, documentation cleanup, and CI/CD quality improvements across two repositories. Delivered non-functional improvements that enhance maintainability and developer experience, enabling on-demand formatting checks and consistent infrastructure documentation.
