I’m an iOS Developer with 2 years of experience building and maintaining scalable iOS applications, with a strong focus on user experience and code maintainability. I’m proficient in SwiftUI, UIKit, and Objective-C, and I prioritize performance optimization, feature development, and legacy system modernization. As a Lead iOS Engineer, I resolve issues and improve UI/UX using QA and business requirements, while keeping quality high through unit testing, code reviews, and clear technical documentation.

I’ve driven measurable impact by reducing application crash frequency by 30% via proactive Crashlytics monitoring and diagnostics. I also helped increase revenue by 15% through cross-platform digital marketing integrations and by optimizing user flows for iOS and Android. Previously, as an iOS Developer, I improved a hotel booking application’s stability and performance—reducing app-issues by 40%—and led analytics, push notifications, cloud messaging, payment gateway integration, and UI/UX enhancements that contributed to a 40% increase in market coverage. As an iOS Engineer intern, I built reusable CocoaPod libraries and improved project efficiency by ~30% using Jira-based workflows and Agile practices.
