Message

At Systems Limited, I develop native iOS applications for fintech and digital wallet clients, including e& money and ZainCash. I build Swift and SwiftUI features for secure payment flows, REST API integrations, and push notifications.

At Joblogic, I developed and maintained iOS and Android apps for a field service management platform. I delivered features including job scheduling, invoicing, compliance tracking, and offline-first data sync, and migrated legacy Objective-C code to Swift and Core Data to SQLite.

I also developed Flutter features integrated into the native iOS app and contributed features to TradeHero. Earlier, I built and supported mobile apps at AcclivousByte and developed Android apps including Urdu Qaida and Relax Player at KhyberCoded.
