I build scalable Android and React Native apps with real-time and offline capabilities.
IndiaWhat I'm looking for
I've built and launched Android and React Native products at Dotsquares Technologies and Aryavrat Infotech, including property management, emergency communication, travel podcast, and live-tracking applications.
At Dotsquares, I migrated a property listing app from Kotlin to React Native with a redesigned UI. I integrated Master Lock and Igloo smart-lock SDKs, ID scanning, biometrics, chat, notifications, authentication, and native Android bridging for property access.
At Aryavrat, I built Attavik and Limons from scratch, contributing to a 30% increase in the company’s app portfolio. I improved Mobitrack’s live tracking through foreground services, Fused Location Provider, and WorkManager, while building offline communication, geofencing, and personalized experiences.
I focus on clean architecture, performance, and user-centric mobile experiences using Kotlin, Java, React Native, Firebase, REST APIs, and Android Jetpack components.
