About Me

Building apps
that matter

I'm a Senior Mobile Engineer with over 6 years of experience crafting polished, high-performance iOS applications. Currently at Systems Limited in Islamabad, I lead modernization efforts for top telecom clients across Pakistan and Qatar.

My expertise spans the full iOS stack — from architecting scalable codebases with MVVM, VIPER, and Coordinator patterns, to reactive programming with RxSwift and Combine. I'm also expanding into Flutter for cross-platform excellence.

Outside of code, I create iOS development content on YouTube, sharing knowledge with the next generation of developers.
