Jadez developed multi-currency support for payment collection in the stripe-terminal-react-native repository, enabling merchants to process transactions in various currencies within mobile payment flows. The work involved updating React-based front end components and integrating TypeScript logic to handle dynamic currency formatting and selection. Jadez ensured that the new feature aligned with backend multi-currency handling, maintaining consistency across the payment stack. By focusing on both UI changes and backend integration, Jadez addressed cross-border checkout friction and expanded merchant reach. The project demonstrated depth in front end development, particularly in mobile UI design and seamless integration with existing backend systems and APIs.
