I help founders and product teams build, rescue, and launch production-ready native iOS apps with Swift, SwiftUI, UIKit, StoreKit 2, Firebase, APIs, SDKs, and App Store/TestFlight delivery. I’m Top Rated on Upwork with 100% Job Success, $10K+ earned, 10 completed jobs, and 9 rated 5.0. My strongest work is native iOS, but I can also build native Android companion apps with Kotlin/Jetpack Compose when a product needs Android parity. Recent work includes: • Launch rescue for a native iOS marketplace: fixed beta blockers, integrated Crashlytics, Sign in with Apple, Stripe PaymentSheet, Apple Pay, backend checkout/order fixes, and App Store release support. • StoreKit 2 modernization for a legacy Objective-C/Objective-C++ iOS app suite, including paid-app-to-freemium entitlement repair for around 2,500 legacy users. • SwiftUI apps shipped to the App Store with StoreKit 2 purchases, SwiftData, private CloudKit sync, TestFlight QA, and production fixes. • Native Android apps with Kotlin/Jetpack Compose, Firebase, maps/location workflows, Google Play testing/review support, and Android parity for iOS-first products. • AI app work with OpenAI API text/image workflows, StoreKit 2 credit packs, SwiftData history, and native iOS UX. • iOS SDK work involving StoreKit 2 transaction monitoring, backend reporting, deduplication, retries, and local persistence. I’m a strong fit if you need: • A new native iOS app built from Figma/API to TestFlight or App Store • AI feature integration: chat, text generation, image workflows, structured outputs, assistants, credits, usage limits, and backend proxy integration • StoreKit 2 purchases, subscriptions, credits, restore purchases, or paywall fixes • Legacy iOS modernization, Objective-C/UIKit cleanup, or messy app rescue • Stripe PaymentSheet, Apple Pay, checkout, cart/order, or marketplace launch support • Firebase, CloudKit, maps, background location, push notifications, or API integration • Native Android parity with Kotlin/Jetpack Compose for an iOS-first product • An iOS SDK, Swift Package, or native integration where reliability matters The best way to start is a focused milestone: audit, bug fix, launch-readiness review, or one feature slice. You’ll get clear communication, practical tradeoffs, and implementation that moves the app closer to production.

I build production iOS apps for founders who need an engineer that thinks about the product, not just the ticket. Most of my clients are early-stage founders or small product teams who have either a half-built app they need to finish, or a clear idea they want turned into something shippable. I own the full execution: architecture, data layer, AI integration, App Store submission. What I bring to a project: — 12 published apps across iOS, macOS, and watchOS — Deep experience with SwiftUI, SwiftData, HealthKit, CloudKit, WatchConnectivity, and on-device AI — RevenueCat and StoreKit 2 for monetization — OpenAI and Apple Intelligence integration — Clean, maintainable code you can hand off to a team later I work best with founders who want a technical partner, not someone who just closes tickets. If you need someone to think through architecture decisions, push back on bad ideas, and ship fast — that's what I do. Currently studying AI Engineering at Stanford (2024–2027). If you have an iOS product to build or a stuck codebase to rescue, let's talk.
