During February 2026, Endoftimee enhanced security and reliability across the hackclub/hackatime and hackclub/site repositories. They developed an OAuth application secret rotation feature, integrating a user interface for secret renewal, admin-level access controls, and Doorkeeper support to ensure only superadmins could rotate secrets. This included UI updates for displaying and copying new secrets, with internationalized flash messages for user feedback. On hackclub/site, Endoftimee resolved a data reliability issue by correcting the API endpoint domain in the data fetch flow, ensuring accurate data sourcing. Their work utilized Ruby on Rails, JavaScript, and HTML, demonstrating depth in backend and frontend development.
