The Personal Expense Tracker is a MERN Stack project that combines Transaction entry and Charts and reports, built with MongoDB. The project follows a clean, modular architecture where the React frontend, Express API, and MongoDB database stay separated, making it easy to test, extend, and present. It showcases practical full stack techniques while producing a working, demo-ready application.
Traditional offline and manual processes for this task are slow, limited to one place, and hard to scale. Without a full stack web approach built on Charts and reports and MongoDB, users cannot access, manage, and share data easily from any device, and there is no centralized way to run the workflow.
This project applies MERN Stack techniques through Transaction entry, orchestrated with MongoDB and Charts and reports. The application is designed for usability and scale, with a responsive frontend, robust API, and clean data layer. It produces consistent, reusable results and can be adapted to related full stack tasks with minimal changes.

Modular full stack app around Transaction entry and Charts and reports
Configurable settings and role based access
Clean REST API with error handling
Responsive interface for all devices
Reusable components for related features
Authentication and data persistence
The project is layered: the client layer builds the UI through Transaction entry; the API layer exposes endpoints with MongoDB and Charts and reports; and the data layer persists information via Export module. Shared auth, validation, and state management modules support all layers, keeping the application robust and easy to extend.
