PROFILE
Jack Hellowell
Jack Hellowell developed and enhanced core testing frameworks for the NHSDigital/personal-demographics-service-api repository over a two-month period. He built a generic patch request testing framework to streamline patient data update validation, refactored existing tests for consistency, and centralized patch body generation utilities using Java and Cucumber/Gherkin. Jack also improved the sandbox testing environment, enabling isolated creation of test patients and stubs to support local development. By refining patch operations for patient name updates and expanding test coverage, he increased data integrity and API clarity. His work emphasized maintainability, test automation, and robust backend development practices throughout the project lifecycle.
