🏦 Bank Management System

The Bank Management System is a secure, scalable, and user-friendly application that simulates real-world banking operations using Spring Boot, Thymeleaf, and MySQL. It incorporates Spring Security for authentication and authorization, JWT for secure token-based communication, and OAuth2 for third-party login options like Google and GitHub. The system provides essential banking features such as deposits, withdrawals, fund transfers, and transaction history, while supporting role-based access control for Admin, Employee, and Customer roles. Its architecture follows a layered design with clear separation between the Controller, Service, Repository, and Security layers, making it scalable for future enhancements like multi-currency support and loan management. Built with a focus on security, user experience, and real-time functionality, it ensures a seamless and safe experience for both desktop and mobile users. A secure, feature-rich, and responsive Bank Management System built with modern Java and web technologies. This project helps manage banking operations like customer registration, account handling, fund transfers, and user role access with a clean UI and robust backend.
