BudgetIQ - A Full Stack Web Application

BudgetIQ is a web application designed to provide users with a comprehensive and secure platform for managing their budgets. It leverages Java, Spring Boot, and React with Material UI to offer a seamless user experience. This app uses role-based authentication and a set of advanced features, including two-factor authentication (email), token refresh, and optimized backend functionality.

Technologies Used

Backend

• Java 17: The core backend is developed using Java.
• Spring Boot: A robust and scalable backend framework.
• Spring Security: Implemented role-based authentication and security features.
• Spring Boot Role-Based Authentication: Utilizes spring-boot-role-base-auth for managing user roles and secure access to resources.
• JWT Tokens: JSON Web Tokens for secure authentication and token refreshing.
• Multithreading: Leveraged for better performance and concurrent processing.
• Optimized Code: Focused on optimized time and space complexity, as well as garbage collection efficiency.
• Global Exception Handling: Centralized exception handling for consistent API responses.
• Email Notifications: Global email configuration for various events (e.g., successful login).
• Two-Factor Authentication (Email): Configured for increased security during login.
• API Response Standardization: Updated the API response structure to ensure consistent and clear data formatting.

Frontend

• React: A JavaScript library for building user interfaces.
• Material UI: A popular React component library for modern, accessible designs.
• Redux: For managing application state.
• Axios: For making API requests to the backend.
