T-Cash
A modern e-wallet mobile app built with Flutter and Firebase, featuring secure authentication, balance tracking, and real-time transactions.
✨ Description
T-Cash is a mobile e-wallet application built with Flutter for Android devices. Developed as my first large-scale mobile programming project for the Mobile Programming course, this app was designed to simulate a real-world digital wallet experience. The project emphasizes secure financial transactions, clean interface design, and smooth user interaction — bringing together key mobile app concepts such as authentication, state management, and data persistence. Beyond its core functionality, T-Cash also serves as a milestone in my journey to mastering Flutter development and building scalable, user-centered mobile applications.
