Omni Connect: Multi-Tenant Service Booking & Subscription Ecosystem
Architected a multi-vendor directory and appointment booking platform with merchant control dashboards, geolocation salon discovery, and RevenueCat subscription paywalls.
The Engineering Challenge
Preventing double-booking race conditions when multiple customers attempt to reserve the exact same service appointment time slot simultaneously.
Managing complex vendor permissions, tiered subscription packages, and client booking histories in a single application.
What I Built & Delivered
Engineered atomic Firestore transaction reservations preventing any concurrent appointment booking conflicts.
Built dynamic geo-fencing salon directory maps filtering nearby providers by rating, services, and immediate slot availability.
Constructed custom vendor management dashboards allowing merchants to configure service menus, pricing, and operating hours in real time.
Integrated tiered subscription paywalls through RevenueCat to monetize premium merchant listings.
