Worked on the ministryofjustice/hmpps-env-configs repository to deliver a coordinated upgrade of the pre-production environment, aligning Delius core, LDAP, API/UI, and UMT services with upcoming production versions. Used Terraform and YAML to manage configuration changes, ensuring that all version updates were traceable through well-documented commits. This approach reduced environment drift and improved the reliability of pre-production testing, supporting faster and more predictable release cycles. The work focused on configuration management and DevOps practices, with careful documentation of upgrade steps to facilitate future maintenance and deployment. No bugs were reported or fixed during this period, reflecting a focused feature delivery.
