Simon Mitchell engineered and maintained cloud infrastructure for the ministryofjustice/cloud-platform-environments repository, focusing on secure, scalable, and auditable platform services. He delivered cross-environment upgrades, including PostgreSQL migrations and Redis enhancements, and standardized Terraform modules to reduce configuration drift. Simon implemented CI/CD automation using GitHub Actions and managed AWS resources such as S3, IAM, and Athena to support data governance and compliance. His work included decommissioning legacy environments, integrating audit tooling, and enforcing tagging and access controls. Using Terraform, YAML, and Docker, Simon’s contributions improved deployment reliability, security posture, and operational efficiency, demonstrating depth in infrastructure as code and DevOps practices.
December 2025 performance highlights: Delivered PostgreSQL 18 upgrades across hmpps-audit, hmpps-auth, and hmpps-SAR environments (dev, preprod, prod); added environment skip-file placeholders; implemented Foundations tagging governance across multiple services; migrated hmpps-auth Docker images to GHCR to enable deployment flexibility; completed IRSA updates for hmpps-auth across environments. Minor fix: corrected spelling in hmpps-audit-prod. These changes improved platform consistency, deployment flexibility, security posture, and governance.

May 2025 monthly summary focusing on key accomplishments, business value, and technical achievements for ministryofjustice/cloud-platform-environments. Primary work this month centered on cost optimization and security hardening through the decommissioning of the HMPPS Users API environments (dev, preprod, prod). End-to-end removal of Kubernetes namespaces, RBAC configurations, quotas, network policies, TLS certificates, and Terraform resources for the hmpps-users environment reduced running costs and the security risk surface. The decommissioning aligns with platform governance and simplifies future lifecycle management of environments.
