Charles Marshall engineered robust DevOps and infrastructure solutions across several Ministry of Justice repositories, including opg-digideps, opg-use-an-lpa, opg-data-lpa, and opg-lpa. He centralized Terraform version management, modernized CI/CD pipelines, and introduced configuration governance to improve deployment reliability and security. Using technologies such as Terraform, GitHub Actions, and AWS, Charles automated VPN allow-listing, streamlined runtime tooling, and enhanced disaster recovery documentation. His work included fixing critical CI workflow bugs, consolidating risk management and service continuity documentation, and implementing version pinning for reproducible builds. These contributions established scalable, maintainable infrastructure and improved operational resilience across cloud-based services.
December 2025 monthly summary for ministryofjustice/opg-lpa: Focused on strengthening service resilience and governance through consolidated Make An LPA service continuity, risk management, and deployment documentation. Delivered architecture updates, disaster recovery and incident response guidance, AWS region failover considerations, IAC/Alpine Docker and PHP deployment readiness, and enhanced load testing and maintenance details. This work reduces deployment risk, improves incident response readiness, and provides clearer governance across the deployment pipeline.

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.

Implemented centralized Terraform version management and improved CI/CD consistency for ministryofjustice/opg-use-an-lpa. Consolidated Terraform version declarations into a single versions.tf, removed direct usage of the .terraform-version file in CI, cleaned up unused inputs in the terraform-version action, and added version visibility to CI logs to improve maintainability, observability, and reliability.

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.
