Worked on integrating StatusList functionality for MDoc and MSO within the walt-id/waltid-identity repository, focusing on enhancing status-aware workflows and policy enforcement. Developed new components, including StatusElement and StatusListInfo, and updated the MDocBuilder and MSO modules to process status lists according to the IETF OAuth status lists draft. The implementation was delivered through two targeted commits, ensuring compliance with evolving standards. Utilized Kotlin for development, applying expertise in API design, cryptography, and data structures to support mobile identity solutions. The work addressed the need for robust status management, contributing to the platform’s extensibility and standards alignment.
