Hire the Best Objective-C Developers
in Pakistan

I am a Senior iOS Developer with 10+ years of experience building high-quality iPhone and iPad applications, primarily using Swift, with good experience in Objective-C for legacy codebases, maintenance, and migration. I specialize in creating clean, scalable, and user-friendly iOS apps that deliver a smooth experience for users and real value for businesses. I have worked on a wide range of iOS projects, including apps with REST APIs, Firebase, in-app purchases, subscriptions, ads, analytics, push notifications, animations, and third-party SDK integrations. My core iOS expertise includes: * Swift, Objective-C, UIKit, MVC, MVVM * REST APIs, JSON, XML, Alamofire * Firebase Crashlytics, Analytics, Remote Config, Messaging * In-App Purchases and subscription-based apps using StoreKit and StoreKit 2 * App Store deployment and release management * Push notifications and deep linking * Local storage using UserDefaults, Document Directory, CoreData and related solutions * Third-party SDKs such as Google Mobile Ads, AdMob, IronSource, Tapdaq, Mixpanel, TikTok Open SDK, and social login integrations * Image loading and caching using Kingfisher and SDWebImage * UI development from Sketch, Figma, UI/UX mockups, and design requirements * Animations using Lottie and GIF-based solutions * Debugging, performance optimization, Xcode Instruments, Time Profiler, and Memory Graph debugging * Git, GitHub, SourceTree, CocoaPods, command line tools, and team collaboration tools such as Trello I am comfortable working on both new applications from scratch and improving existing apps. I can help fix bugs, improve performance, refactor old Objective-C code, migrate features to Swift, integrate APIs, resolve App Store issues, and build production-ready iOS features. I enjoy solving complex problems because they keep my skills sharp and help me deliver better solutions. My goal is always to write reliable code, communicate clearly, and deliver work that meets both technical and business requirements. I also have previous experience with HTML, CSS, JavaScript, C, C++, QML, Qt, PhoneGap, and Adobe Photoshop, which helps me understand cross-platform, UI, and product-related requirements more effectively. If you are looking for an experienced iOS developer who can build, improve, or maintain your app with quality and professionalism, I would be happy to help.

I’ve been working as an iOS Developer for about 6 years, creating and maintaining real Apple iOS apps using Swift, SwiftUI, and UIKit. I’ve worked on iPhone app projects, including fintech platforms like JazzCash, which is one of the biggest mobile wallets in Pakistan with millions of users. I helped build and improve important payment features there. I’ve mostly worked on production apps where performance, reliability, and security really matter. I’ve also worked on PayMax, a digital payment platform that focuses on secure transactions and merchant services, and EDYOU, which is a private social network for college students. I work on connecting REST APIs, handling payment processes, improving app performance, and keeping the app’s structure clean by using MVVM and Viper. I write Swift code that’s clear and easy to maintain. I also make sure to set up Unit Testing and UI Testing, and I build systems that can grow without breaking when they’re running in production. For me, collaboration is really important. I team up with designers, backend developers, and product people to build features that work smoothly and can handle the load from development all the way to App Store release and TestFlight testing. If you need someone who can create and support scalable iOS apps, work with tricky APIs, and get reliable products out to the App Store, I’m the one for the job.

Your vision deserves a technical partner, not just a developer. I specialize in transforming ideas into high-performance applications across the entire digital ecosystem: mobile, web, and desktop. I believe great software is a blend of cutting-edge technology and thoughtful user experience. Whether it's a consumer-facing iOS/Android app, a mission-critical web dashboard, or a native Windows/macOS application, I build with a focus on strategy, scalability, and long-term success. I build everywhere your users are. → Mobile: Native (Swift, Kotlin) & Cross-Platform (Flutter, React Native) → Web: Modern JS Frameworks (React, Angular, Vue) & Backend (Node.js, Python) → Desktop: Electron, .NET MAUI, Native APIs Ready to build the right solution, not just the easy one? Get in touch.
