I am a freelance iOS developer with extensive experience in native development for Apple platforms. For more than a decade, I have been specializing in Swift and Objective-C for iOS, macOS, and watchOS, driven by a passion for clean, maintainable code and outstanding user experience.
My focus lies on building high-quality, testable, and scalable software solutions using SwiftUI, UIKit, Combine, and Swift Concurrency (async/await). I have a strong commitment to code quality, proven experience with Unit, UI, Snapshot, and Contract testing, and in-depth knowledge of setting up and maintaining CI/CD pipelines using GitHub Actions and Fastlane.
I value teamwork, open communication, and collaboration across disciplines. Working in agile environments (Scrum, SAFe) has strengthened my ability to bridge technical and creative perspectives. My background as a Media Engineer allows me to combine design awareness with technical precision — creating robust, elegant, and user-centric applications.
