    paper Spending tracker

    AI-Powered MPESA Spending Tracker

    Designed and developed a personal finance application that helps users gain clear visibility into their spending habits, specifically tailored for digital transactions through MPESA. The project was built to address a common problem in personal finance: the difficulty of understanding where small, frequent expenses accumulate over time.

    The application provides a simple and fast way to track daily spending while leveraging AI to extract transactions from raw MPESA statements and suggest personalized budgeting categories based on user spending patterns. The system prioritizes clarity and minimalism, avoiding complex budgeting rules and instead focusing on making financial behavior visible and actionable.

    The platform is built with a modern full-stack architecture using Next.js for the frontend and Spring Boot for the backend, containerized with Docker for easy deployment. AI-powered features are integrated through the Groq API to enable fast transaction parsing and intelligent categorization.

    Key Features

    AI-powered extraction of transactions from MPESA statements

    Automated budget category suggestions based on spending behavior

    Clean dashboard showing daily, weekly, and monthly spending trends

    Minimal input expense logging for fast daily use

    Self-hosted architecture ensuring full data ownership
