Money Manager

MoneyManager is a full-stack personal finance application built with Spring Boot on the backend and React with Tailwind CSS on the frontend. The backend follows a layered architecture - Controllers → Services → Repositories — using Spring Data JPA for database interaction. Authentication is stateless, implemented via JWT tokens with a custom JwtRequestFilter validating every request. The database has four core entities: Profile, Category, Income, and Expense, linked via foreign keys with cascade delete. On the frontend, Axios handles HTTP communication with interceptors that auto-attach the Authorization header and redirect to login on 401 responses. The /filter endpoint supports dynamic querying by date range, keyword, and sorting using Spring Data’s Sort abstraction. Charts are rendered with Recharts (LineChart, BarChart, PieChart), providing visual analytics on the dashboard. The app runs on MySQL locally and PostgreSQL on Render in production
