During November 2024, Dominic contributed to the hackclub/hcb repository by developing an admin-focused user experience enhancement. He implemented an admin-only age indicator on the Settings page, which displays a visual cue next to the birthday field to signal whether a user is a teenager. This feature, built using Ruby on Rails and front-end development skills with HTML, enables administrators to quickly identify underage users, streamlining governance and reducing manual review time. Dominic’s work focused on role-based UI elements and non-invasive interface changes, demonstrating a targeted approach to improving admin workflows while maintaining a clean and unobtrusive user experience.
