Building scalable Android & iOS applications.

I’m a React Native Developer with 3+ years of experience building scalable, production-ready Android and iOS applications.

I specialize in React Native, TypeScript, and Expo Bare Workflow, focusing on performance, clean architecture, and real-world integrations like payments, maps, notifications, and authentication.

I also build backend services using the MERN stack for full-stack solutions and integrations.
