Worked on the ministryofjustice/cloud-platform-environments repository to deliver support for the court-case.updated event type across multiple AWS notification channels. Using Terraform and HCL, implemented infrastructure as code changes to enable accurate handling of updated court-case events through SNS topic subscriptions, domain events queues, and SNS subscription filter policies. The approach included end-to-end wiring and validation across development, preproduction, and production environments, with environment-specific commits to ensure a safe and controlled rollout. This work enhanced the reliability of cross-channel event propagation, allowing downstream systems to automatically respond to updated court cases without requiring manual intervention or additional configuration.
