About
I am an iOS engineer with around five years of taking apps from an empty Xcode project to a global App Store release. I am the sole iOS engineer on Magibook, a premium subscription reading platform, and the solo founder of four shipped App Store products across up to 50 locales.
Day to day that means owning the whole thing — SwiftUI architecture, audio and EPUB engines, CloudKit sync, subscription monetisation, A/B tests, store metadata and the release itself.
