Sagar Upadhyay

I am a dedicated iOS developer with 5+ years building mobile apps across fintech, insurance, and lifestyle domains. I focus on delivering performant, user-centered experiences with attention to code quality and maintainability.

I specialize in Swift, SwiftUI, UIKit and modern patterns like MVVM and clean architecture, and I use tools such as Xcode, Firebase, Alamofire and Git to ship production-ready apps. I write unit tests and design modular code to support scalable product growth.

I have led core modules and end-to-end features — from onboarding and QR payments to claims workflows and in-app purchases. My work has helped reduce onboarding time by 40%, supported scaling to 1M+ users, increased time-in-app by 25%, and enabled 50K+ digital claim submissions with 60% faster processing.

I thrive on cross-functional product teams that value user experience, performance, and testable architecture. I seek opportunities where I can contribute technically and help improve product quality, user metrics, and developer velocity.
