Who I Am

Noorul Akbar

I'm an Android Engineer (SDE-2) based in Bengaluru with a track record of shipping production apps that are fast, reliable, and loved by users. My core stack is Kotlin, Jetpack Compose, and Kotlin Multiplatform.

I care about the parts users feel — cold start time, smooth 60fps scrolling, crash-free sessions — and the parts engineers feel — clean architecture, modularization, and testable code. I've taken apps from legacy XML to modern Compose, bridged fitness hardware to Android over BLE, and built a cross-platform SaaS solo.

Strong in MVVM/MVI, Clean Architecture, Coroutines/Flow, offline-first design, and performance profiling.
