Product ownership and engineering depth
I built GlowUp’s iOS product from the ground up and ran it for three years of App Store releases and data-informed iteration. That included the SwiftUI app, subscriptions, analytics, CI/CD, localisation into more than 30 languages, and the initial Node and TypeScript middleware around its generative image backend.
At Motorway, I worked in a large multi-squad mobile organisation on a SwiftUI marketplace app used at national scale. I owned a companion App Clip that went on to handle more than 70% of the organisation’s photo uploads. At Westpac, I worked in the core architecture team on modular boundaries, UIKit-to-SwiftUI migration, Swift 6 adoption and production performance.
I have also led iOS work in health, built and supported a commercial SDK embedded by tier-one banks, and repeatedly built CI and release systems that make shipping safer rather than harder.
