I build and scale iOS subscription apps, from MVP to millions of users.

I owned Astopia’s iOS app end-to-end for more than three years, scaling the consumer subscription product from MVP to 1M+ users, a 4.7★ rating, and a top-three Astrology App Store position.

I rebuilt its codebase into a modular MVVM architecture spanning 23 scene modules and roughly 1,800 Swift files, then owned StoreKit 2 subscriptions, dynamic paywalls, LLM-powered chat, AI image generation, live chat, analytics, and offline data. I also built Fastlane and GitHub Actions delivery pipelines supporting 100+ releases, with automated testing, TestFlight delivery, and Crashlytics monitoring.

I enjoy shipping polished iOS experiences across UIKit, SwiftUI, widgets, Live Activities, localization, and reliable networking. I’ve also open-sourced 20+ portfolio apps and mentored an intern iOS engineer into a full-time role.
