I’m putting together a simple, reliable app that lets players book courts and organise friendly matches for both futsal and badminton. At its core the product needs a clean calendar view, time-slot booking, team or opponent matching, and automatic reminders. I’m happy for you to choose the tech stack you know best—whether that’s Flutter, React Native, Swift/Kotlin, or something else—as long as the finished build runs smoothly on both iOS and Android and can scale later to a modest web dashboard. What will convince me you’re the right fit is straightforward: show me past work that proves you’ve built scheduling, booking, or sports-related apps before. Live links, screenshots, or store listings are perfect; a concise note on the toughest issue you solved in those projects is even better. I’m not driven by a tight deadline, so feel free to propose a sensible, staged roadmap that covers prototype, testing, and release at a pace that suits quality development.
