Fintech / Full-Stack Development
ExpensAI
An intelligent expense management application combining receipt OCR, policy validation, spending insights, and streamlined expense workflows.
Project overview
A full-stack expense workflow designed to reduce friction between receipt capture, validation, and useful spending context.
- React Native
- Expo
- FastAPI
- PostgreSQL
- Firebase
Problem
Expense workflows often require repetitive data entry and manual policy checks. ExpensAI explores a more streamlined, mobile-first alternative.
Application architecture
The application combines a React Native and Expo interface with backend API integration, PostgreSQL, and Firebase-supported services.
OCR & policy logic
Receipt OCR helps bring expense information into the workflow, while policy-based validation and smart alerts support review rather than replacing it.
Insights & workflow
Expense recording, category-level spending insights, and alerting are designed as practical features within the larger expense-management flow.
Mobile & backend integration
The React Native and Expo interface brings expense recording and receipt capture to mobile. Backend API integration connects the interface to policy validation, stored expenses, and spending insights.
