Apr 1, 2026

April 2026 monthly summary: Delivered two focused improvements across two repositories that enhance security, stability, and cost-efficiency. Key outcomes include CI/CD policy hardening for hmpps-resettlement-passport-ui (SHA-pin of setup actions and removal of the Trivy dependency check) and the decommissioning of Pingdom monitoring in cloud-platform-environments (removal of Pingdom Terraform resources). These changes reduce build instability, align with security strategy, and eliminate obsolete monitoring, delivering clearer governance and lower maintenance costs. Demonstrated capabilities across CI/CD, IaC, security policy enforcement, and cross-repo collaboration.

May 1, 2025

May 2025 monthly summary for ministryofjustice/cloud-platform-environments focusing on the Jobs Board Reporting UI Repository Migration. The change consolidates the jobs board reporting flow to a UI-based implementation by migrating namespace configuration across dev, preprod, and prod to reference the UI repository and removing API-related certificates. This signals archiving/de-prioritization of the API component and reduces maintenance surface area while improving security through tighter certificate handling and a unified UI path.
