In September 2025, delivered centralized governance of automated dependency updates (Dependabot) across a broad set of GOV.UK repositories, shifting from a disablement approach to a scheduled cadence that balances security and stability. Implemented ecosystem-specific update schedules (Bundler and npm daily; Docker and GitHub Actions weekly) with explicit ignore rules for Ruby in Docker updates. This included lifecycle management of Dependabot configurations (removing and re-adding dependabot.yml) to support auditable, repeatable policy changes. Restored automated dependency updates after disruptions across multiple services, reducing exposure to out-of-date libraries and improving patch velocity. The work demonstrates strong cross-team coordination, governance, and hands-on configuration of CI/dependency tooling to deliver measurable business value while minimizing noise in development workflows.

April 2025 monthly summary for alphagov/govuk-infrastructure focusing on infrastructure stability and risk mitigation. The primary change this month was the rollback of Grafana RDS Terraform adjustments to revert to a known-good state due to issues with relocating resources in the Terraform state. This prevented destabilizing changes to the Grafana RDS setup while preserving security and networking configurations.
