I need a cohesive digital presence built from the ground up: a responsive website and a companion mobile application that run natively on both iOS and Android. The product’s core purpose is to let users organise events and drive engagement through an “event-quiz earn money” feature—attendees answer live quizzes during an event and instantly see cash rewards reflected in their in-app wallet. The flow I have in mind: • Visitors land on the website, browse upcoming events, and register. • Once registered, they download the mobile app (iOS and Android) for on-the-go access. • During an event the quiz module opens, tracks correct answers in real time, and credits winnings that can be withdrawn via common payment providers. Clean UI/UX, smooth real-time syncing between website and apps, and robust security around wallet payouts are essential. You are free to pick the tech stack—Flutter, React Native, Swift/Kotlin or a similar modern framework—so long as performance is solid on both platforms. Deliverables 1. Fully designed and coded responsive website. 2. iOS application compiled and ready for App Store submission. 3. Android application compiled and ready for Google Play submission. 4. Shared backend with APIs handling user accounts, event data, quiz logic, payouts and basic analytics. 5. Source code, build instructions and minimal documentation so my team can maintain the product after launch. If you have previous experience marrying event management with gamified elements, please mention one example; I’m specifically interested in seeing how you tackled real-time scoring or monetary rewards. Let me know the estimated timeline for an MVP and any assumptions you need from my side (branding, payment gateway credentials, hosting, etc.).
