Worked on the nhsuk/manage-vaccinations-in-schools and NHSDigital/manage-vaccinations-in-schools-testing repositories, focusing on documentation clarity and API routing reliability. Improved the README by updating instructions for test user creation, providing practical examples, and refining parameter usage, all documented in Markdown. Addressed a routing bug in the Mavis testing API by standardizing all testing endpoints under a unified /api/testing/ prefix, which streamlined test fixture integration and reduced misrouted requests. Utilized Python and Shell scripting for performance testing and DevOps tasks, ensuring that documentation and API structures were consistent, maintainable, and aligned with best practices for testing workflows and developer onboarding.
