Worked on enhancing OAuth documentation for the vcita/developers-hub repository, focusing on JWT-based client authentication. Consolidated and clarified the use of JWT access tokens, JWKS endpoint integration, and Private Key JWT within the OAuth flows, updating the apps API documentation to support secure, token-based authentication. The work involved multiple documentation commits that introduced new OAuth parameters, aiming to streamline developer onboarding and reduce integration complexity for partners. Leveraged skills in API development, API documentation, and security, with a strong emphasis on OAuth and JSON. These enhancements improved the clarity and security of authentication processes for external developers and partners.
