Expense Tracker App
A full-stack expense tracker with user authentication, transaction logging, and PDF upload for automated analysis.
Project Overview
Built a feature-rich expense tracking platform that allows users to securely log in, record income and expenses, and upload transaction PDFs for automatic data extraction and analysis. Integrated a PostgreSQL database for persistent storage and used Django for backend APIs. The frontend, developed in React, offers a clean and responsive user interface for efficient financial management.

Development Process
Planning & Requirements Gathering
Identified common user pain points in managing expenses. Outlined key features like auto-parsing statements, charts, and categorization. Sketched wireframes and designed database schema.
Backend Development
Built the backend using Django. Integrated PDF parsing using Python libraries, and stored transactions in a PostgreSQL database hosted on Supabase. Implemented authentication and authorization.
Frontend Development
Created a clean and responsive UI using HTML, CSS, and JavaScript. Integrated Django templates with dynamic views for displaying data and interacting with the backend.
Testing & Deployment
Tested PDF uploads, form validations, and data integrity. Deployed the project on Render and connected it to Supabase for persistent storage.
