Crafting apps that
stand the test of scale

I'm a Senior Mobile Engineer with 6+ years of experience building production iOS applications using Swift, SwiftUI, and UIKit, as well as cross-platform apps with React Native. I specialise in architecting scalable, maintainable codebases that teams can grow with confidence.

My work spans fintech remittance platforms used by millions of users, health-monitoring apps with Apple Watch integration, eCommerce platforms, VPN clients, and LMS systems. I bring the same rigour to a brand-new greenfield app as I do to rescuing a legacy codebase that's been stalled for years.

I live in Karachi, Pakistan and work remotely with teams across the US, EU, and beyond. Clean CI/CD pipelines, test-driven development, and mentoring junior engineers are as much a part of my toolkit as code.
