What I'm looking for

I seek roles where I can lead mobile product quality and scalability, work with mission-driven teams, mentor engineers, and deliver reliable, user-focused iOS experiences.

I am an experienced iOS developer with a track record of building and scaling high-quality mobile applications used by hundreds of thousands of users. I focus on delivering secure, reliable, and intuitive solutions using Swift, SwiftUI, UIKit, and Firebase.

At Housecall Pro I led migrations from Objective-C to Swift and SwiftUI, integrated Firebase for realtime data and authentication, and maintained a 98% crash-free rate while supporting 200,000+ monthly active users. I have also developed apps for enterprise and banking clients and delivered modern interfaces across iPhone and iPad.

I have led and grown teams as an App Development Manager, recruiting and managing cross-functional groups to deliver native iOS and Android products on time. I hold an MBA in Management and a postgraduate degree in Software Engineering, and I seek mission-driven environments where I can continue to improve product quality and user experience.
