Banking Mobile Application A full-stack mobile banking application built with React Native, Node.js, Express, and MongoDB. The application provides a mobile banking experience with secure authentication, biometric authentication, push notifications, account management, transactions, and backend API integration. The transaction system supports network-aware processing. Transactions initiated while offline are handled as pending and synchronized when connectivity is restored, helping maintain a reliable transaction experience across changing network conditions. The application also provides financial statistics, metrics, and expenditure analysis to help users understand their spending patterns. It supports USD, NGN (Naira), and EUR currency conversion and exchange-rate information. I developed the React Native mobile application, built and integrated the backend REST API, implemented authentication and data handling, connected the application to MongoDB, and deployed the backend for production use. The project demonstrates end-to-end mobile application development, combining a responsive React Native interface, secure authentication, network-aware transactions, financial analytics, currency conversion, push notifications, backend APIs, and database integration.

The platform is deployed with the frontend on Vercel and backend on Render.
