FinanceOS — AI-Powered Personal Finance Platform

FinanceOS is a full-stack personal finance management platform built to help users organize their expenses, track transactions, and better understand their spending habits through an interactive dashboard.

The application is built using the MERN stack — MongoDB, Express.js, React, and Node.js. It includes expense and transaction management, financial dashboards, category-based analytics, and interactive charts for visualizing spending patterns.

A key part of FinanceOS is its integration of AI-powered financial insights. The application uses the Gemini API to provide a conversational interface through which users can interact with their financial information and receive useful insights in natural language.

FinanceOS also includes receipt scanning using OCR technology, allowing information from receipts to be extracted and used for expense tracking. This reduces manual data entry and demonstrates the integration of external technologies into a full-stack application.

Learning & Development

FinanceOS represents my progression from building smaller projects to developing a more complete full-stack application. Through this project, I gained practical experience in frontend development, backend API design, database management, third-party API integration, OCR, data visualization, and AI integration.

The project allowed me to bring these technologies together into a single practical application rather than treating them as isolated concepts.
