Worked on the companieshouse/psc-data-api repository to enhance privacy and data quality in the Companies House PSC Data API. Developed a feature that conditionally exposes the date of birth, showing the full date for register views while restricting list endpoints to only month and year, improving compliance and user safety. Addressed data type inconsistencies in test data by reverting problematic changes and aligning formats with expected outputs, which strengthened test reliability. Utilized Java for backend and API development, focusing on robust data transformation and comprehensive testing practices. These improvements enabled safer data sharing and streamlined future development and iteration cycles.

Key outcomes include targeted DOB handling for register vs list endpoints, safer API responses, and more reliable test data aligned with expected formats, enabling safer data sharing and faster iteration.
