What I'm looking for

I'm seeking Senior or Staff iOS Engineer roles to drive platform engineering at scale.

At CloudAngles / PersonifyHealth, I architected a modular enterprise iOS health platform with Clean Architecture, MVVM, and the Coordinator Pattern. Its 15+ feature modules achieved 92% code reusability.

I built its networking layer with RESTful and GraphQL APIs, URLSession, Swift Concurrency, and Combine, enabling real-time synchronization for 5M+ users. I also improved performance and security, including reducing crashes by 60% and protecting health data with encryption, SSL pinning, and biometric authentication.

At PayPal, I architected PayPalUIKit, a design system of 75+ reusable components adopted across the iOS ecosystem serving 30M+ users. I also helped migrate 45+ components from UIKit to SwiftUI and introduced snapshot testing across 80+ components.

Earlier, I delivered iOS applications across health, e-commerce, transportation, and streaming. At AppyPie, I developed ARKit features and a MapKit and CoreLocation service; at Fluper, I worked on transportation and media streaming apps. I'm seeking Senior or Staff iOS Engineer roles focused on platform engineering at scale.
