Over a two-month period, this developer focused on security-driven modernization within the ministryofjustice/modernisation-platform-environments and ministryofjustice/modernisation-platform repositories. They engineered the transition from a public-facing Application Load Balancer to an internal load balancer, leveraging AWS, Terraform, and HCL to enhance internal routing and reduce external exposure. Their work included deprecating legacy infrastructure and integrating private subnets for improved security. In addition, they strengthened access governance by provisioning PreProd access for security teams and implementing new 'view-only' and 'read-only' roles using JSON-based configurations. These efforts established a more secure, auditable, and scalable platform environment with robust access controls.
