Matchmaking & Dating Platform

About This Project

Seven (InstaDating) is an innovative matchmaking mobile application that revolutionizes online dating through time-based pools and algorithmic matching. The platform operates on a scheduled daily pool system (9:00 PM PST to 10:00 PM PST) where exactly 14 users (7 male, 7 female) join for a 3-minute matchmaking session. Users can view 7 opposite-gender profiles and set preferences by dragging profiles up or down. The app implements the 'Stable Marriage Problem' algorithm to guarantee 100% match success for all participants. Built with React Native for cross-platform mobile experience (iOS and Android), the platform features real-time Socket.io connections for live pool management, Firebase for instant messaging between matches, and intelligent bot integration to ensure pool completion. Users can experience the app through a demo mode, upload up to 5 profile pictures, report inappropriate content, and block unwanted connections.
