What I'm looking for

I seek senior, remote-friendly iOS roles where I can lead teams, build scalable Swift/SwiftUI apps, optimize performance, mentor developers, and drive measurable product growth in collaborative environments.

I am a senior iOS developer with 10+ years building high-performance mobile applications using Swift, SwiftUI, and Objective-C. I focus on MVVM, MVC and Clean Architecture to produce scalable, maintainable code and strong UI/UX experiences.

I have led teams and mentored developers, delivering apps with millions of downloads and measurable product impact — improving app rendering speed by 40%, speeding API response times by 50% through data caching, increasing MAUs by 25% and driving 40% product revenue growth in three months.

I value clean code, performance tuning, and cross-functional collaboration. I enjoy mentoring engineers, setting architectural standards, and adopting cutting-edge iOS technologies to drive continuous improvement and user engagement.
