What I'm looking for

I seek challenging mobile roles where I can lead full-cycle app development, improve performance and maintainability, collaborate cross-functionally, and deliver scalable products for growth-focused teams.

I am a passionate and results-driven iOS and cross-platform developer with deep expertise in Swift (UIKit), SwiftUI, Objective-C, React Native, and Flutter.

I have led full software development lifecycles for multiple apps, working independently and within large cross-functional teams to deliver production-ready applications deployed to the App Store and Google Play.

My work includes architecting systems, enhancing performance and maintainability, conducting peer code reviews, and cultivating strong client relationships through direct communication and ongoing support.

Notable projects span English-language learning platforms, creative collaboration apps, survival-community apps, and multimedia/video apps, demonstrating a consistent focus on scalability, efficiency, and long-term stability.
