React Native Developer | Mobile Engineer

Building fast, reliable, and scalable mobile applications with React Native, TypeScript, Expo, and Kotlin.

I'm a React Native Developer with 4+ years of professional experience building and maintaining cross-platform mobile applications for Android and iOS.

I work across the mobile development lifecycle, from application architecture and reusable UI components to API integration, state management, third-party SDKs, performance optimization, debugging, testing, and app store releases.

I've built applications involving real-time communication, service booking, authentication, push notifications, maps, secure local storage, and real-time data synchronization.

I'm also expanding my native mobile expertise with Kotlin, Android, Jetpack Compose, and React Native's New Architecture, including Fabric, Turbo Modules, JSI, and native bridging.
