I am an iOS developer focused on delivering high-impact, user-centric mobile products. I build fast, scalable, and maintainable iOS applications using modern Apple technologies — Swift, SwiftUI, UIKit, Swift Concurrency, Combine, and RxSwift — applying clean architectural patterns (MVVM, MVC, MVP) to ensure long-term stability and clarity of code. I have extensive experience working with REST APIs, local persistence, push notifications, analytics, and mapping frameworks, and I also manage the full release pipeline using Fastlane. Beyond coding, I contribute to architecture planning, technical decisions, code reviews, and evolving team standards. I enjoy delivering polished, reliable products with strong performance and smooth UX, and I thrive in collaborative environments that value quality and maintainability.…I am an iOS developer focused on delivering high-impact, user-centric mobile products.
