What I'm looking for

I'm looking to build scalable, high-performance Android products, lead and mentor teams, and collaborate across functions in agile environments with strong engineering standards.

I've built and maintained scalable Android applications for Photon, NTT DATA, CyQureX Systems, and startups across e-commerce, healthcare, IoT, and cybersecurity.

At Photon, I design robust Android applications, lead project execution, and help teams deliver high-performance products on time. I previously led 5–10 professionals using Jira and Scrum, including a fitness-tracking pilot for regional and non-regional clients.

My work includes biometric SSO, Firebase Cloud Messaging, IBM Watson configuration, secure chat, geofencing, offline data tracking, REST APIs, payment gateways, and real-time order tracking. I use Kotlin, Java, Android Jetpack, MVVM, MVP, Room, Retrofit, Volley, Google Maps, and Firebase to create maintainable mobile experiences.

I'm focused on code quality through reviews, standardization, CI/CD practices, root-cause analysis, and mentoring developers. I work closely with cross-functional teams to deliver user-centric Android solutions that meet enterprise standards.
