VaultAI

SecureBank is a full-stack financial management platform that combines practical money tracking with interactive financial literacy education and AI-powered fraud detection. We were inspired by the realization that many people struggle with managing their finances not because they lack tools, but because they lack understanding and engagement. Instead of building just another budgeting app, we created a system that allows users to deposit money, transfer funds, track spending across categories, and monitor security threats — while also earning rewards by answering financial literacy questions. The backend was built using Node.js, Express, SQLite, bcrypt for password hashing, and JWT for secure authentication, ensuring that each user’s data is protected and properly authorized. On the frontend, we designed an interactive dashboard that dynamically updates balances, transactions, budget progress, and fraud alerts in real time. One of our biggest challenges was transitioning from simulated frontend data to a fully persistent backend while implementing proper authorization checks to prevent unauthorized access. We also developed a rule-based fraud scoring engine that analyzes transaction amounts and merchant patterns to classify transactions as safe, flagged, or blocked. Through this project, we learned how real authentication flows work, how secure API design prevents vulnerabilities, and how financial education can be embedded directly into product experience. SecureBank ultimately aims to empower users not just to manage their money, but to understand it, protect it, and grow it with confidence.
