I am a Senior iOS Developer with extensive experience building and maintaining scalable iPhone and iPad applications using Swift, SwiftUI, UIKit, Combine, and modern iOS architectures. I have hands-on experience with REST and GraphQL APIs, Swift 6 and Swift Concurrency, performance optimization using Xcode Instruments, CocoaPods-to-SPM migration, iOS SDK upgrades, authentication with Okta and Auth0, reusable UI components, and unit testing.

I enjoy solving complex technical problems, improving application performance and maintainability, and collaborating with cross-functional teams to deliver high-quality products.
