September 2025 monthly summary focused on strengthening CI/CD reliability and code quality across the GovUK One Login repos. Delivered security hardening for CI/CD by pinning the SonarQube Action to a known secure commit SHA, and standardized tooling updates to ensure consistent, up-to-date static analysis across all services. No user-facing feature changes were introduced; the work centered on tooling upgrades, security, and maintainability.

Month: 2025-07 Focus: Upgrading and refactoring the Lambda-driven process that updates ECS task definitions and synchronizes environment variables with SSM parameters for the hmrc-kbv service. The work improves deployment reliability, security posture, and maintainability through better structure and tests.

February 2025 — Delivered security policy hardening, centralized policy management, and CI/CD reliability improvements across the IPv-CRI portfolio. Key outcomes include: (1) origin load balancer exclusions from regional FMS policy across ipv-cri-uk-passport-front-v1, ipv-cri-dl-front, and ipv-cri-fraud-front with baseline/generated_at updates to tighten security controls; (2) centralized FMS policy and WAF integration for API Gateway in ipv-cri-bav-api, including tests updates and reconciliation of REST API WAF associations; (3) upgraded CI/CD tooling across the portfolio (SonarCloud/SonarCube actions) to mitigate deprecation risks and maintain code quality checks without affecting application logic; (4) Linux/ARM64 Docker build workflow hardening in ipv-stubs by explicitly targeting linux/arm64 and correcting build command order, improving multi-arch reliability; (5) enhanced CI pipeline reliability across multiple repos through consistent policy tagging, baseline updates, and timestamp refreshes.

January 2025 — govuk-one-login/ipv-cri-address-front: Delivered Deployment Infrastructure Enhancements to improve reliability, scalability, and cost awareness. Key features include stabilizing canary deployments by updating pre-commit tooling and suppressing the canary-specific cfn-lint E3056 warning in deploy/template.yaml; expanding ECS auto-scaling across all environments using ForecastOnly predictive scaling to gather data and align resources for potential cost optimization. The changes were implemented via two commits focused on tooling and policy expansion across environments.

November 2024 performance highlights: Completed broad CI/CD modernization across 9 ipv-cri services, focusing on upgrading GitHub Actions to current versions, upgrading artifact handling to v4, and strengthening security checks. Implemented deployment naming constraints to prevent Lambda name length issues, improved artifact management, and reduced build flakiness through streamlined workflows. This work delivers higher reliability, faster feedback loops, and stronger security posture while enabling smoother Lambda deployments and artifact pipelines.
