During February 2025, James Bishop focused on security and data privacy enhancements for the companieshouse/psc-data-api repository. He addressed the risk of internal identifier leakage by modifying the IndividualFullRecord transformation to exclude internal_id fields from API responses, ensuring sensitive data remained protected. Additionally, he mitigated a known security vulnerability by upgrading the Spring Boot starter dependency, maintaining API stability without requiring code changes. His work demonstrated strong skills in Java, backend development, and dependency management, with careful attention to data transformation safeguards and compliance. The changes improved the API’s privacy posture while preserving existing functionality and test coverage.
