April 2025 monthly performance-focused summary for NHSDigital teams. Highlights include the delivery of end-to-end performance tests across key user journeys, improvements to data traceability and retrieval, and targeted CI/code quality enhancements. Also, stabilizing fixes restored production-ready behavior and dev tooling accessibility, reducing risk from prior PRs.
