I designed and built the whole product end to end: the owner dashboard, a branded WiFi login page for every ISP (12 designs), and the payment flow that puts customers online the moment they pay, on Android and iPhone. Customers can pay by card, bank transfer, mobile money or crypto (Bachs, Paystack, M-Pesa), check their own data balance, redeem vouchers, and try free trial plans. It runs on MikroTik routers and serves 21 ISPs today.
