Conceptualized and designed Circles—community groups where military families connect based on shared interests, duty stations, or lifestyles (Military Moms, Fitness Groups, PCS Support). I created a flexible privacy system with three tiers: Public (open joining and visible content), Private (request-to-join with private content), and Secret/Classified (invite-only and invisible to non-members). This privacy architecture addresses the sensitive nature of military life while enabling authentic community building. The interface makes discovering, joining, and managing groups intuitive, with clear visual indicators for privacy levels and engagement activity.
