I’m ready to launch a full-stack platform that mirrors the TesterUp experience: a web portal plus native apps for both iOS and Android. The core flow is simple—users register, browse paid tasks, complete them, then collect rewards—yet the build must be clean, scalable, and secure. Here’s what I need from you: • A responsive website that offers the same journey as the mobile apps. • Native iOS and Android apps built with a maintainable codebase (Swift/Kotlin, React Native or Flutter—your choice, so long as performance remains smooth). • Core modules: – User sign-up & login with strong authentication and social sign-on. – Task management dashboard where I can post, edit, and track tasks in real time. – Reward system that credits users instantly and logs all transactions. • Seamless integrations: payment gateway for cash-outs, social platforms for easy sharing/referral, and analytics hooks (GA4/Firebase or similar) to monitor user behaviour and KPIs. • An admin panel where I can manage users, tasks, payouts, and view analytics without touching code. • End-to-end deployment to production servers and app stores, plus hand-off of documented source code. Acceptance criteria will centre on flawless registration, zero-error task submission, accurate reward calculation, and a successful payment test from sandbox to live. If you’ve built gamified or reward-based systems before and can move quickly while keeping the UX polished, let’s talk timelines and milestones.
