2025-09 Monthly summary focused on CI/CD reliability and maintenance for ministryofjustice/opg-data-lpa. Fixed a critical CI pipeline issue by correcting the path to the terraform-version GitHub Action (added the actions/ subdirectory), ensuring the destroy_workspaces.yml workflow runs reliably. This reduces CI failures, shortens feedback cycles, and lowers deployment risk. Commit 4bc870c287e7f30e96cddf6c05a916f54930b77c.

November 2024 (2024-11) focused on strengthening secure remote access and enabling seamless Prisma VPN connectivity for authorized users. Delivered a Terraform-based update to the default allow list in the ministryofjustice/opg-digideps repository, adding the Prisma VPN IP range to permit traffic by default. This reduces manual configuration, accelerates onboarding for authorized users, and strengthens the security posture by clearly permitting Prisma VPN traffic. The change was implemented via a single commit (7b5eca1ac6cb3d7296a816fc86744ae815e789cf) with the message: 'Add primsa vpn range to the default allow list'. No major bugs were reported/fixed in this scope. Technologies/skills demonstrated include Terraform (infrastructure as code), access control through allow-list management, Git versioning and commit hygiene, and value-driven collaboration with security and ops teams.
