Robert McCormack delivered a coordinated pre-production environment upgrade for the ministryofjustice/hmpps-env-configs repository, focusing on aligning Delius core, LDAP, API/UI, and UMT services with upcoming production versions. He applied configuration management and DevOps practices, using Terraform and YAML to manage and document the deployment changes. By upgrading multiple service versions in a traceable manner, Robert reduced environment drift and improved the reliability of pre-production testing. His approach emphasized clear documentation and commit traceability, supporting faster release readiness. The work demonstrated a methodical application of infrastructure as code principles to streamline environment consistency and accelerate the software delivery pipeline.
