WatchMyWallet

Overview

WatchMyWallet is a cross-platform personal-finance app for tracking expenses, automating recurring transactions and budgeting per category — with real-time sync across devices and an offline-first mobile experience.

What I did

• Built the mobile client in React Native / Expo with offline-first local storage.
• Developed a Node/Express + MongoDB backend with Socket.IO for live multi-device sync.
• Implemented recurring transactions and per-category budgeting logic.
• Created a Next.js marketing site for the product.
