Hi, I’m Ravi Kumar Sharma
Android engineer shipping AOSP-based in-vehicle experiences and cloud-connected features — with Jetpack-style architecture and modern Kotlin APIs — plus Flutter packages, Chrome extensions, and open source on the side.
About
I’m Ravi Kumar Sharma (@sharmark9931), a Software Development Engineer at
Jio Platforms Limited in Bengaluru. I focus on Android platform development:
embedded AOSP UIs for connected vehicles, cloud-backed features, and production-grade Kotlin codepaths —
using Jetpack libraries and modern architecture patterns day to day.
Outside of work I publish Flutter packages on pub.dev, ship Chrome extensions, and write technical articles on Medium — always chasing interfaces that feel fast, clear, and a little delightful.
Skills
Strong emphasis on Android & Jetpack for production vehicle and mobile stacks, plus Flutter for packages and shipped apps.
Android & Jetpack
Professional experience building AOSP-based Android surfaces (digital clusters, companion flows) with Kotlin and Java. I lean on Jetpack components — Navigation, ViewModel, LiveData/Flow, Room, WorkManager, and Jetpack Compose where appropriate — for maintainable UI and background work alongside platform APIs (Bluetooth, notifications, maps, and more).
Flutter development
Dart & Flutter for cross-platform UI — packages on pub.dev, the JNVK alumni app, and Medium articles. In parallel with platform work, I tie this to AvniOS (Avni / in-vehicle digital cluster stack) and the public JioBharat app on Google Play — the Jio Bharat keypad-phone experience — which matches the simulator I shipped in my SDE-1 role.
