During September 2025, Daniel Sanson developed privacy-aware Date of Birth handling for the companieshouse/psc-data-api repository, focusing on conditional data exposure for register and list endpoints. He implemented logic in Java to ensure the day component of birth dates is shown only in register views, while list endpoints display only month and year, enhancing data privacy and compliance. Daniel also addressed data type inconsistencies in test data, aligning formats and reverting problematic changes to maintain reliability. His work combined API development, backend engineering, and data transformation, resulting in safer API responses and more robust, format-consistent test data for ongoing development.
