Hire Objective C freelancers in United States

I have been a developer for more than 20 years. I have Bachelor’s degree in Computer Science. I really enjoy creating apps in the Apple ecosystem. I have had various types of experience in my development career. But specifically relating to iOS, I have written iOS apps that interface with hardware via bluetooth, such as the KoamTec handheld barcode scanner. I have also used communication technologies such as JSON-RPC 2.0 and RESTful services. My most recent coding experience has mostly been with Swift, but I started out using Objective-C and I am currently learning SwiftUI. I have used iOS technologies such as UIKit, CoreLocation, CoreData, AVFoundation and WebKit. I most commonly use MVVM and Coordinator design patterns for development. I am mainly interested in remote positions.
