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.
