• ⚙️ Building real-time mobile experiences with Realm, Ditto, and React Native
• 🧵 Offloading heavy data transformation from JS thread to native Kotlin
• 🛰️ Architecting full-stack systems that are fast, scalable, and elegant

Empowering frontline workers through AI-powered mobile platforms.

• Built a React Native app with 100% offline access using Realm
• Delivered MVP in just 6 weeks 🚀
• Optimized query performance → 40% faster load times
• Helped increase user retention by 25%
