Adam implemented JWT issuer support for the ministryofjustice/opg-data-lpa-store repository, enabling the opg.poas.use issuer for broader integration scenarios. He refactored the issuer verification tests to a table-driven format, which improved test coverage and maintainability by validating multiple issuer and subject combinations efficiently. Working primarily in Go, Adam focused on backend development and API security, ensuring robust token validation and access control for LPA data storage services. His work addressed the need for secure and flexible authentication mechanisms, enhancing the repository’s ability to handle diverse JWT issuers while maintaining high standards for security and test reliability throughout the codebase.
