June 2026 monthly summary for UKHSA-Internal data dashboards: Delivered key features, strengthened security/governance, and improved CI/CD reliability across two repositories. Key outcomes include enhanced observability, centralized secrets management, and more stable deployment pipelines, directly supporting faster incident response and stronger governance. 1) Key features delivered - Audit Logging System for Permissions and Model Updates (data-dashboard-api): Implemented auditable tracking of user permissions and model changes, improving accountability and traceability (commit c419d19a31ef740a0b8152ee44831f82708ee92d). - CloudWatch Logging Infrastructure for ECS Services (data-dashboard-infra): Established CloudWatch log groups and properly sequenced subscription filters to ensure reliable log data collection and auditability, with iterative refinements (commits including dependency handling and naming updates). - Centralized Secrets Management for ECS Services (Entra integration): Introduced per-environment AWS Secrets Manager resources for Entra environment variables to centralize secrets management (commits b5cf82c3b64a798341a3c154213b8411c5822fc3; 0f1c6cdaf14f41af5b026e3232ff34ecae3fdb61). - CI/CD Workflow Stability and PR Reference Management: Improved CI workflow reliability and PR reference handling to ensure correct base references and consistent checkout behavior (commits ce2cb8406da7c556c27c262f5ee1798c097b8987; 158bccaf9acc2ea240ea53bf5e0c9e8ddb9f10fb; 96bc76129014c9331e3135fda29bbd988003063a). 2) Major bugs fixed - Resolved intermittent CI checkout and base-reference issues affecting PR builds by stabilizing PR workflow references and dependency tests (CI/CD-related commits). - Addressed iteration-level configuration problems in CloudWatch log subscription dependencies to ensure auditable and reliable log delivery. 3) Overall impact and accomplishments - Improved governance and security posture through auditable permission and model-change tracking. - Enhanced observability and incident response capabilities via centralized logging infrastructure. - Reduced deployment risk and increased confidence in releases through stabilized CI/CD processes. - Scaled readiness for ECS-based services by centralizing secrets management and standardizing logs. 4) Technologies/skills demonstrated - AWS CloudWatch Logs, ECS, and Secrets Manager (Entra integration). - Infrastructure as Code and iterative experimentation with dependencies and log group configuration. - CI/CD best practices, PR workflow management, and automated testing. - Focus on business value: traceability, security, observability, and deployment reliability.

May 2026 monthly summary for UKHSA-Internal/data-dashboard-infra: Focused on security, observability, and operational hygiene. Delivered a modular Audit Logging Infrastructure with S3 lifecycle management (IAM roles/policies, CloudWatch log groups, Kinesis Firehose to S3) and secure transport with access logging. Refactored Terraform code for naming consistency and IAM hygiene, introducing resource prefixes and removing account-wide changes. Tightened access control by adding Ian Rufus' IP to the allow list. Fixed S3 logging delivery policy ARN to ensure logs are correctly delivered. Ongoing cleanup included modularization of S3 bucket management and updates to log references and lifecycle rules (e.g., SonarQube) to optimize storage and cost. Overall, improved security, auditability, and maintainability, enabling faster on-boarding of infra changes and reduced operational risk.
