My expertise lies in Swift, SwiftUI, Combine, and modern Apple frameworks, allowing me to launch products from scratch and set up CI/CD pipelines effectively.

Throughout my career, I have built health-focused iOS applications, designed core features independently, and collaborated closely with cross-functional teams to ensure maintainability and scalability. I thrive in fast-paced environments, always staying ahead with the latest iOS technologies and focusing on clean architecture.
