Juan Antonio G.

Senior iOS Developer with over 15 years of experience in the Apple ecosystem.

I develop native applications in Swift and Objective-C for iPhone, iPad (iPadOS), Apple Watch (watchOS), and Apple TV (tvOS), using both UIKit and SwiftUI.

I work with the main architectures: VIPER, MVP, MVVM, and MVC, adapting each one to the real needs of the project, from initial MVPs to highly complex production applications.

Proficiency in the complete stack of Apple frameworks: Core Data, SwiftData, CloudKit, HealthKit, StoreKit, ARKit, CoreML, CoreBluetooth, CoreLocation, MapKit, CoreMotion, WidgetKit, AVFoundation, and Vision. I have trained Machine Learning models and integrated CoreML into real projects.

For external integrations, I have worked with Firebase, Realm, Keychain, REST APIs (URLSession, Alamofire), as well as third-party hardware like GoPro cameras (Open GoPro) and DSLR cameras (Cascable).

Professional workflow: CI/CD with Jenkins, SPM, and CocoaPods for dependency management, testing with XCTest, and complete App Store publishing.

Experienced in leading development teams, performing code reviews, and advising on architectural decisions. Available for projects in Spanish and English.

I will be happy to clarify any doubts you may have and advise you on what you need so that you have no problems starting or continuing with your project.
