Papan Manna

Mobile application developer with 6+ years of experience building scalable, high performance mobile applications. I specialize in Android(Java/Kotlin) and have hands-on experience working with React Native and React.js on hybrid applications.

I enjoy solving complex technical problems, exploring new technologies, and continuously improving my skill set. Currently expanding my expertise in React Native, while staying deeply rooted in Android best practices and clean architecture.

Always curious, always learning, and motivated by building reliable products that make a real impact.
