Month: 2025-09 — Delivered infrastructure cleanup in NHSDigital/electronic-prescription-service-account-resources, removing the Cloudfront Logging Bucket, its policy, and related outputs from account_resources.yml. This reduces unused infrastructure, lowers ongoing cloud costs, and simplifies future provisioning. The work demonstrates a focus on cost optimization, security hygiene, and maintainable IaC practices.

December 2024: Focused on delivering core infrastructure and release automation for the NHSDigital/eps-vpc-resources repo. Key work included a CDK-based AWS VPC networking stack (subnets, flow logs, security) with environment-aware packaging and release workflows, plus automation to update Jira and Confluence release notes. A bug fix addressed missing actions in the release notes workflow to ensure reliable propagation. These efforts improved environment consistency, reduced manual toil, and strengthened release traceability across environments. Technologies demonstrated: AWS CDK, GitHub Actions, IaC, Jira/Confluence automation, VPC networking, logging, and security configurations.
