Arnab B

Android developer with 7+ years of building apps that people actually use — from logistics and biometrics to e-commerce and IoT.

I work across the full lifecycle: architecture decisions, feature development, Play Store releases, and keeping things stable in production. Comfortable with Kotlin, Java, Jetpack, Firebase, and MVVM, and I've led delivery on multiple live apps across different industries.
