GoPay: Fintech Billing and Payments App Design

GoPay brings recurring bills, e-invoices, payments, and wallet activity into one mobile product. The design challenge was to make dense financial information understandable without slowing down the tasks people came to finish.

I mapped the main journeys around account setup, bill discovery, payment, transaction history, receipts, card management, notifications, and security. The interface uses progressive disclosure so users see the amount, status, and next action first, with invoice detail available when they need it.

The final design includes a reusable component system, light and dark visual modes, searchable invoices, biller profiles, and clear payment states. I produced the product flows, wireframes, high-fidelity UI, Figma prototype, and developer-ready handoff.
