Senior Android Engineer at InnovationM, leading Airtel Fiverse and cutting map rendering time by 60% with 10K+ markers.

At InnovationM, I lead the Android team building Airtel Fiverse, a fiber-planning app used by field teams across 500+ cities. I cut map rendering time by 60% with 10K+ markers and helped improve survey accuracy from 75% to 94%.

On Saregama Padhanisa, I raised crash-free stability from 69% to 99% and removed 500+ ANRs. I also integrated live video lessons and built a waveform audio player.

Previously, I built Android apps at Squareboat Solutions, Techtonic Enterprise, and Zappkode Solutions, including a Bluetooth/BLE truck telemetry app and offline-first learning and farmer-assistance apps. My work spans Kotlin, Jetpack Compose, app architecture, maps, and connected-device experiences.
