Worked on the qgis/QGIS repository to enhance the OAuth2 authentication experience by simplifying the verification flow and improving post-verification messaging. Focused on reducing user friction and support overhead, the work involved removing unnecessary interface elements and implementing auto-close or redirect behaviors after authentication. Leveraged C++, Qt, and frontend development skills to deliver concise, actionable user guidance following OAuth2 verification, ensuring users clearly understood next steps. All changes were delivered through incremental, well-documented commits, supporting maintainability and future enhancements. The work emphasized reliability and clarity in the authentication path, with a focus on user experience rather than bug fixes.
