Who I am

Mobile engineer focused on ownership and production grade delivery. I've spent 6 years building apps that ship, scale, and stay alive in production from fleet management platforms in the UAE to live sports apps used by hundreds of thousands across South Africa, the UK, and the US. Native Android is my core expertise, with 3 years of Flutter experience across both Play Store and App Store releases.

The person

I'm a Senior Android Engineer based in Lahore, Pakistan with 6 years of professional experience shipping production mobile apps.

My work spans fleet management, live sports, aviation scheduling, roofing operations, and e-commerce. I've built products used across the UAE, South Africa, UK, and the US.

My primary focus is native Android using Kotlin, Jetpack Compose, and Clean Architecture. I bring 3 years of Flutter/Dart with 3 cross-platform apps on both stores. Beyond mobile, I have backend exposure through ASP.NET Core with SQL Server, having built full-stack fleet systems from scratch.
