Juline S.
iOS & Apple Watch Developer | SwiftUI, App Store, AI Features
I build native iOS and Apple Watch apps in Swift and SwiftUI, from the first screen to the App Store release. This summer I built an Apple Watch + iPhone app for a US client: a scoring engine on the watch, HealthKit workout sessions with live heart rate and calories saved to Apple Fitness, sign-in handed from the phone to the watch, and a Supabase backend with offline-safe sync, shipped through TestFlight. My own app, Budget & Tax: Expense Tracker, is live on the App Store. It's built in SwiftUI with Live Activities and the Dynamic Island, a share extension, Shortcuts, AI receipt scanning and four languages. Work I'm a good fit for: - New iOS or watchOS apps and MVPs, split into milestones you can test on TestFlight - Features in an existing app: HealthKit, WidgetKit, Live Activities, notifications, StoreKit, Face ID and Keychain - App Store submission, App Review rejections, signing and Xcode build problems - On-device or API-based AI features (OCR, vision, LLMs) that keep user data where it belongs I test every build on a real iPhone 15 Pro Max and Apple Watch Series 9. I'm on UTC+8, so you'll usually wake up to progress. Send me the details and I'll tell you honestly whether it's a fit and what it would take.
