PakistanWhat I'm looking for
I am a results-driven Senior iOS Engineer with seven years building scalable, secure mobile applications across Fintech, Healthcare, E‑Commerce, and Mobility. I design and implement robust architectures using Swift, SwiftUI, UIKit, MVVM, VIPER, and Clean Architecture to deliver production-ready apps.
At VaultsPay I built the iOS app from scratch with programmatic UI and SnapKit, implemented core payment flows, KYC via Sumsub, and strong encryption measures. At CareCloud I led major features for BREEZE used by 600,000+ users, reduced bug backlog by 90%, and guided a migration from UIKit to SwiftUI.
I excel in performance optimization, modernizing legacy codebases, CI/CD and release management, and cross-functional collaboration. I bring analytical leadership, strong communication, and a track record of delivering stable, secure mobile products to regulated environments.
