Kartik Rana

I'm a React Native and React JS developer with 5+ years of experience building high-performance, cross-platform mobile applications for iOS and Android. I specialize in React Native, ReactJS, TypeScript, JavaScript, Redux, and mobile performance optimization.
At my current role, I led the complete overhaul of a seller-facing mobile product — growing monthly active users from 1.3L to 1.5L, cutting app size by 36%, and maintaining a 99.7% crash-free rate across a high-traffic consumer app.
Previously, I built a telemedicine platform — integrating real-time chat (PubNub), video consultations (OpenTok), and live health tracking for a patient-facing healthcare product.
Always interested in meaningful conversations around mobile engineering, interesting product challenges, and collaborative opportunities.
Feel free to connect or drop me a message.
