Ah Padel
Mobile-first tournament management platform (React Native app + NestJS microservices backend) for sports events.
The brief
Build a tournament management mobile app for the padel sports market, enabling organisers to create and manage multi-format tournaments (starting with Knockout) with player registration, payment collection, draw generation, match scheduling across courts/slots, score tracking, and participant communication — delivered by a 2-person engineering team on a Developers On Demand engagement.
What we built
A comprehensive sports tournament management platform branded "Ah Padel" — a React Native mobile app backed by a NestJS microservices API. The system supports six tournament formats (Knockout, Round Robin, Groups+Knockout, League, Franchise, Americano), full player registration with Razorpay payments and GST, automated bracket/draw generation with court-slot scheduling, real-time score management, leaderboards, national ranking tournaments (NRT) with UTR v2/IPF ranking integration, multi-channel notifications (push, email, WhatsApp, SMS), geo-based tournament discovery with multi-filter search, admin panel with PDF/CSV export, a franchise team tournament model with auto-registration, and a bird's-eye scheduling view. The platform was live-supported for real tournaments including the JOI franchise tournament.
The platform is live in production with all six tournament formats (KO, RR, GKO, League, Franchise, Americano), Razorpay payment integration with live keys, push/email/WhatsApp notifications, national ranking tournament support, franchise team management, geo-aware tournament discovery, PDF/CSV export, admin panel APIs, bird's-eye scheduling view, and v2 scheduling engine. Real tournaments including JOI franchise format have been run on the platform.
