About

Seven years in Swift, still shipping.

I'm a Senior iOS Developer with 8+ years building high-performance, user-friendly apps in Swift, SwiftUI, UIKit and Objective-C. I'm most at home in MVVM and Clean Architecture, wiring up REST APIs, hunting performance bottlenecks, and taking apps end-to-end through App Store review.

Lately I lead as well as build — mentoring a mobile team, gathering requirements with product, and turning Figma into pixel-perfect, responsive screens. I care about the parts users never see: crash-free sessions, tight memory, and releases that just work.
