Problem

Many people struggle to keep track of their finances due to inconsistent expense logging and a lack of clear, real-time insight into their spending habits.

Solution

I built a mobile budget tracking app that allows users to record income and expenses, automatically handle recurring transactions, and view up-to-date financial summaries at a glance.

Technical Decisions

React Native + Expo for cross-platform support and faster iteration
Local-first data handling to ensure instant calculations and offline usability
Structured transaction models to support recurring entries without duplicating data logic
Derived state for summaries to keep totals accurate and performant

Challenges

Implementing recurring transactions in a way that stays predictable and avoids double-counting, while keeping calculations accurate as users edit or delete entries.

Outcome

The app provides a clear and responsive way to monitor personal finances and serves as a foundation for advanced features such as spending trends, monthly reports, and AI-driven insights.

Future Improvements

Add data visualization features such as charts and graphs to illustrate spending patterns over time.
Implement cloud sync and user authentication for secure access across multiple devices.
Introduce budgeting goals and alerts to help users stay within their financial limits.
