Who I Am

Building apps that serve
millions of users

I'm an iOS Developer specializing in Swift, SwiftUI, and UIKit with 5.6 years of hands-on experience across fintech, banking, and healthcare. I've contributed to platforms at PayPal and Citi Bank that serve millions of active users daily.

I own complete feature lifecycles — from architecture decisions and API integration to performance tuning and App Store release. I spearhead large-scale migrations from Objective-C to SwiftUI, applying Clean Architecture principles that reduce technical debt and improve long-term maintainability.

Early adopter of GenAI-assisted development, leveraging Claude AI and LLM tooling to accelerate code refactoring, documentation, and delivery on complex enterprise projects.
