Senior iOS developer with 7+ years of shipping apps
I'm a passionate Senior iOS Developer with 7+ years of experience crafting scalable, user-focused mobile applications. My work spans media-intensive domains like photo manipulation, audio/video editing, finance tools, utilities, and wellness apps, where performance, smooth media handling, and a great user experience are critical.
I've scaled products to 5 million monthly active users while maintaining a strong 4.6 average rating across app stores. I lead end-to-end iOS development, collaborate cross-functionally with designers, product, and backend teams, and mentor junior developers to help them grow into strong contributors.
I'm always exploring the latest iOS technologies (SwiftUI, Swift Concurrency, new frameworks), contributing to open source when I can, and staying sharp through tech blogs, WWDC, and developer conferences. Outside of code, you'll find me hiking the trails of the Himalayas.
