October 2025 monthly summary: Delivered key features, governance improvements, and environment hygiene across two repositories (ministryofjustice/keyworker-api and ministryofjustice/cloud-platform-environments). Highlights include enabling Slack notifications for production deployments in CI/CD, introducing CODEOWNERS for governance and faster code reviews, adding a README compliance badge to align with MOJ standards, aligning RBAC across live environments for correct permissions, and decommissioning outdated manage-key-workers Kubernetes namespaces to reduce maintenance burden. No user-facing bugs were fixed this month; placeholder commits were the only minor no-op changes observed. Impact includes improved deployment observability, streamlined code reviews, reduced blast radius, and readiness for audits. Technologies/skills demonstrated include CI/CD automation, Git governance, RBAC and Kubernetes namespace management, and repository compliance practices.
