React Native Mobile App: We designed an iOS and Android mobile app with an extremely playful, lightweight UX, allowing children to trace Hebrew letters on screen and receive immediate visual feedback.
High-Concurrency Backend: We built a REST API using Node.js and Express hosted on AWS to track the progress of over 8,000 active students concurrently.
Offline-First Architecture: We implemented a local SQLite database within the app so students could study without an internet connection and sync their school progress once Wi-Fi is detected.
