I build high-performance native iOS apps from architecture to App Store.
PakistanWhat I'm looking for
I've led end-to-end iOS delivery for XiQ, a B2B sales platform, improving app performance by 66%, achieving 100% crash-free sessions, and helping integrate an AI chatbot that increased user engagement by 25%.
Across i2c, InvoZone, Sixlogics, and DirectFN, I've built and shipped native iOS products for fintech, cybersecurity, health and wellness, booking, social, and sports. My work includes RevBits ZTN, Planet Cricket, XiQ Sales, Stats24, Flexspace, and JustButler.
I build in Swift, SwiftUI, UIKit, and Objective-C using MVVM and Clean Architecture, with REST integrations, testing, performance optimization, and full App Store delivery.
I've also mentored cross-functional mobile teams, partnered closely with product, backend, design, and QA, and turned Figma prototypes and stakeholder feedback into responsive, production-ready experiences.
