I'm a professional software developer from California. I do projects alone, discreetly, with respect to privacy. Write code from a scratch in Swift. Do code reviews in Swift/Objective-C. Can upgrade your code to version compliance. Can rewrite your code from Java, Objective-C, C++, C# into Swift. I'm comfortable with the majority of native frameworks (Cocoa, CoreAnimation, UIKit, SpriteKit, MetalKit, AVKit, Network). I can find a replacement for a third party framework you use with a native one.
