Overview
01 . The Challenge
The client needed an email app that could compete with established players — fast, end-to-end secure, and capable of handling thousands of emails without lag. Rendering long lists on mobile and multi-device synchronization were the primary technical challenges.
02 . The Solution
We used React Native with optimized list rendering via FlashList, implemented E2E encryption for email body content, and real-time sync through websockets. An offline-first architecture ensures users stay productive even without a connection.
