I need a full event-management ecosystem built from scratch and published. The scope covers three mobile apps plus a responsive website, all working seamlessly together on Android, iOS, and the web. Deliverables • User mobile app – must make event discovery smooth and allow in-app ticket purchasing. • Organiser mobile app – organisers should be able to create events, manage ticket sales, and review basic analytics right from their phones. • Scanner mobile app – a lightweight app focused on QR-code scanning at the gate. • Website – public pages for browsing and buying, plus separate log-in areas for users, organisers, and an admin dashboard. • End-to-end testing across devices and browsers. • Store listing & deployment for both Google Play and the App Store. Core expectations --scalability - it should able to manage large scale users – One shared code-base or different code (React Native, Flutter, or similar cross-platform tech) to keep maintenance simple. We can discuss if different code for each platform – Secure, real-time database and payment integration. – Clean, modern UI that is similar to the Eventbrite experience yet keeps branding flexible. – Handover of source code, build instructions, and basic documentation. – Final payment released only after all apps are ready and the website is ready and functioning as per requirement. If you have proven experience shipping production-ready cross-platform apps with integrated payment flows, let’s talk timelines and milestones so we can get this platform in users’ hands.
