As a mobile software developer, I have 11 years of experience and am competent in Multi-Threading Programming in Swift(ObjC) and the expert knowledge of Dispatch (GCD) & Combine, SwiftUI having a proven track record on App Store: 2 games, 1 utility, 1 business app. (This is called Performant App Development.)
