Worked on backend systems for walt-id/waltid-identity and keycloak/keycloak, focusing on credential format support and authorization detail handling. Delivered features in Java and Kotlin to enhance interoperability, such as adding sd_jwt_dc credential parsing and improving serializer validation for better error handling and alignment with oid4vci specifications. Addressed JWT header management to prevent security issues and ensure correct token formation. Refactored OID4VCAuthorizationDetail processing in Keycloak’s Authorization Details API, simplifying response structures and removing unused constants to improve maintainability. The work emphasized robust API development, cryptography, and OAuth2/OIDC integration, reducing technical debt and supporting future extensibility.
January 2026: Keycloak repository focused on simplifying authorization detail handling to improve maintainability and downstream integration readiness. Delivered a refactor of OID4VCAuthorizationDetail processing in the Authorization Details API, removing unused constants and streamlining the response structure to support easier future changes and clearer client contracts. This work reduces technical debt, enhances code readability, and sets a foundation for more robust OIDC4VCI flows.
