Mar 1, 2026March 2026 monthly performance summary for NHSDigital/eligibility-signposting-api. Delivered core feature enhancements, robust deployment workflow improvements, and security hardening, enabling safer, faster releases and improved data processing. Key features and fixes were implemented with a focus on business value, reliability, and maintainable code. Key features delivered: - X-Ray Subsegments Enhancement: Added custom subsegments for X-Ray, plus imports and cleanup; pyright exclusions; formatting; and a decorator workaround for generators where applicable. - Kinesis Stream Buffer Integration: Merged PR introducing Kinesis Data Stream as a buffer for Firehose to improve data ingestion throughput and reliability. - ELI-702: Signing, Deployment Workflow and Permissions: Introduced new signing resources, attached to Lambda, updated workflow to sign and upload before deployment; expanded GitHub role permissions with new policy; renamed to valid, and added dev/exceptions handling. - Security and Configuration Hardening (ELI-702): Consolidated security/config hardening including restricted permissions, env/workspace handling adjustments, broadened ARN usage for config actions, temporarily disabled signing enforcement, and Checkov/workflow suppressions management. - Code Ownership Update (ELI-707): Added CODEOWNERS file to designate repository ownership. Major bugs fixed: - Reverted to old behaviour where an error is required, ensuring errors surface as intended (ELI-BUG). This change stabilized error handling and reduced silent failure modes in deployment and runtime paths. Overall impact and accomplishments: - Improved reliability and visibility across data ingress (X-Ray) and processing (Kinesis), enabling consistent SLAs for eligibility data processing. - Strengthened security posture and governance with tighter permissions, robust signing workflow, and clear ownership, reducing risk in CI/CD and configuration management. - Accelerated safe deployments through a signing-before-upload approach and enhanced automation, lowering the chance of regressions. - Clear ownership and accountability established via CODEOWNERS, easing maintenance and onboarding. Technologies/skills demonstrated: - Python tooling refinements, static checks (pyright), and formatting hygiene; generator decorator handling removed where necessary. - AWS data services: Kinesis Data Streams, Firehose integration; IAM permissions and policy expansion. - GitHub Actions workflows, signing automation, and deployment orchestration. - Security scanning and policy management (Checkov) and suppression handling; environment/workspace configuration changes. - Code governance with CODEOWNERS and repository hygiene.

Feb 1, 2026February 2026: Delivered two core enhancements for NHSDigital/eligibility-signposting-api — enhanced observability and more reliable deployment workflows. The API Gateway logging/auditing upgrade improves troubleshooting, security auditing, and compliance by providing richer, compact JSON access logs. The pre-prod deployment gating reduces release risk and speeds up delivery by ensuring deployments only run under defined conditions. Together, these changes improve operational stability, accelerate incident response, and reinforce governance around API services.
