About Arjun

I'm a mobile developer with 6 years of experience shipping cross-platform and native apps for iOS and Android. My primary toolkit is React Native for cross-platform work, with deep native knowledge in Swift and Kotlin for performance-critical features. I've shipped apps used by millions and I obsess over smooth animations, offline-first architecture, and pixel-perfect UX.
