Worked on the hoppscotch/hoppscotch repository to enhance the reliability and security of OAuth2 authentication flows. Focused on backend development using TypeScript and JavaScript, the work addressed critical issues in OAuth2 password flow by ensuring that scope parameters are handled according to RFC 6749 standards. Improved the encoding of Basic authentication headers to correctly process spaces and special characters, strengthening client credential security. These changes reduced support friction and improved integration reliability for end users. The approach demonstrated expertise in API authentication, secure header encoding, and adherence to OAuth2 protocols, contributing to a more robust authentication infrastructure.
