Premium Card – Digital Card Management & Payments (iOS)

Premium Card is a fintech app for managing digital cards and making secure, reliable payments. I worked on the iOS application, developing card-management features, secure transaction flows, and dependable payment processing. The app integrates payment gateways with encrypted transaction handling and connects to backend financial APIs over REST. Built in Swift using an MVVM / Clean Architecture approach with Dependency Injection, the codebase emphasizes maintainability, testability, and stability, backed by crash monitoring to keep production quality high — giving users a smooth, confident way to manage their cards and complete payments.
