Senior iOS & macOS Engineer with 5+ years building production apps, forensic platforms, Network Extensions, MDM, and high-performance data systems.
PakistanWhat I'm looking for
I’m a Senior iOS & macOS Engineer with 5+ years of experience building and shipping production Apple-platform software. My work spans native Swift, SwiftUI, UIKit, macOS, networking, security, and data-intensive systems.
At PureLogics, I’m directing the native Swift rewrite of RECON ITR, a macOS forensic imaging and triage platform, architecting core systems for Apple Silicon, Intel/T2, APFS, evidence processing, and concurrent volatile-data collection.
At Pligence, I designed and shipped a production-ready Per-App VPN SDK for iOS, researched macOS Per-App VPN, and contributed to a custom MDM solution. I’ve also worked on iOS products at Joblogic, modernizing and refactoring production applications.
I focus on architecture, performance, reliability, and maintainable engineering practices. My work includes reducing CI/CD time from ~30 minutes to 12 minutes and improving network request latency by ~45% through collaboration with backend engineering. I’m particularly interested in challenging iOS/macOS engineering problems involving performance, security, networking, and complex data systems.
