BlinkDish is a meal subscription marketplace connecting users with home kitchens for daily tiffin delivery. Built with React Native (User, Vendor, and Rider apps), Firebase backend, and a web admin panel. Features include subscription management with pause/resume, kitchen discovery with ratings, real-time order tracking, payment integration, and automated delivery notifications. Designed the full product architecture, wrote the product bible, and resolved complex multi-role data flow across three separate apps.
