Hi everyone! 👋
I’m Arunkumar, a Senior iOS Developer with 10+ years of experience building high-quality, scalable, and user-friendly iPhone/iPad apps.
I specialize in:
• Swift, SwiftUI, Combine, Objective-C, UIKit
• Modern app architecture (MVVM, Clean Architecture)
• API integration, performance optimization, and smooth UI/UX
• App Store deployment, CI/CD, and testing
If you're looking to:
✅ Build a new iOS app
✅ Add features to an existing product
✅ Fix crashes, improve performance, or clean up the codebase
✅ Migrate from Objective-C to Swift or UIKit to SwiftUI
I’m currently taking on new freelance/contract work.
Let’s connect and build something amazing together!
