Simonnorris1
Worked on the NHSDigital/manage-vaccinations-in-schools-testing repository, delivering a robust performance testing and automation framework for a vaccination management system. Over nine months, developed and maintained features such as dynamic session pagination, large-organization load scenarios, and end-to-end workflow automation, while addressing reliability and data integrity through extensive bug fixes and refactoring. Leveraged technologies including JMeter, Groovy, and YAML to implement scalable CI/CD pipelines, containerized test environments, and comprehensive data management scripts. Enhanced test coverage and observability, streamlined configuration management, and improved documentation, resulting in a maintainable, efficient system that supports rapid iteration and reliable performance validation at scale.

Sep 1, 2025September 2025 (NHSDigital/manage-vaccinations-in-schools-testing) delivered a focused set of features and reliability improvements enabling a smooth transition into the new academic year cycle, alongside performance/CI enhancements and a cleanup pass to reduce maintenance risk. Key outcomes include project bootstrap and baseline setup, the introduction of new academic year changes, and substantial enhancements to performance/test configuration. End-to-end workflow capabilities were expanded with nurse journey, consent journey (STS), and a full workflow, complemented by JMeter artifact verification for easier auditing. Data processing stability improvements and readability/maintainability changes were implemented, along with a caching step to accelerate builds/tests and general quality improvements across the codebase. A thorough cleanup of legacy performance-test scripts and artifacts was performed to reduce maintenance overhead and risk.
