Worked on improving documentation and example accuracy for the openid/OpenID4VP and openid/OpenID4VCI repositories, focusing on credential issuance and client identification flows. Addressed a documentation bug by updating the client ID example to use the x509_san_dns format, ensuring alignment with the specification and reducing developer confusion. Enhanced Notification Request documentation by clarifying user actions and refining terminology, such as replacing 'deleted' with 'rejected' to better reflect the credential lifecycle. Utilized Markdown and technical writing skills to deliver precise, traceable updates. The work emphasized API design clarity, reducing integration ambiguity and support overhead for developers working with OpenID credential protocols.
