I need a complete system—web and Android—that lets users buy products and then collect a small cash reward every day simply for having made that purchase. After checkout their balance should grow automatically, and they can boost it further just by logging in each day; no surveys, videos, or other gigs are involved. Core flow: • Responsive website where visitors browse / search items, add to cart, pay, and see a “daily earnings” counter activate the moment the order is confirmed. • Android app that mirrors the same journey and pushes login-bonus reminders via notifications. • Secure wallet module showing accrued rewards, withdrawal history, and pending payouts. • Admin dashboard to load new products, set profit rates, pause or resume the daily accrual rule, and approve withdrawal requests. • Standard e-commerce elements—user registration, OTP or email verification, order tracking, multiple payment gateways, coupon handling—should be in place. • Code may be native Java/Kotlin or a cross-platform stack like Flutter with a PHP/Laravel or Node.js backend; pick whichever you are strongest in, just keep it scalable and well-documented. Hand-over is complete only when: the website is live on my domain, the APK is accepted in Google Play internal testing, automated daily crediting runs without cron errors for 48 hours, and I receive source code plus setup instructions. If this sounds clear and you have built similar cashback or reward engines before, let’s get started.
