Project Description

In this project, we’ll build a budget application, BudgetBuddy, using the FERN stack—Firebase, Express, React, and Node.js. This app will seamlessly integrate real-time updates through Firebase’s database, enabling users to manage their finances with instant visibility. We’ll create the frontend, powered by React, which will offer an interactive single-page experience, allowing users to navigate and update their budget effortlessly. Additionally, we’ll provide CRUD (create, read, update, and delete) functionalities for income, expenses, and budget allocation.

We’ll use Express and Node.js at the backend to manage a RESTful API that’ll securely handle data operations. We’ll use Firebase to handle user authentication to ensure data privacy, while server-side validation will guarantee accurate and reliable financial records. We’ll also create comprehensive reports to allow users to visualize their financial patterns and expenditure trends, enabling them to make informed decisions for better financial management.
