Your iOS app was rejected, crashes after an update, or its subscription flow isn't working? I fix existing apps and get them through App Store review. RESULTS YOU CAN CHECK - 66 completed Upwork projects and 44 consecutive 5-star reviews - 11 years building iOS apps in Swift,Objective C, UIKIT and SwiftUI, with apps live on the App Store - Cleared App Review after rejections: a hardware app (demo video to Apple's requirements) and a chat app (message screening, block and report) - 5 paid consultations on iOS, Firebase and AI integration, all rated 5 stars I'm Ghullam, a senior iOS developer. I add AI features with OpenAI APIs and Core ML, and take apps from TestFlight through App Store approval. WHEN CLIENTS CONTACT ME Most come with an app that's already live: crashes after an iOS update, a subscription flow that keeps getting rejected, a Firebase backend that's out of sync, or a previous developer who disappeared. I read the code first, find the root cause, and ship a stable fix. I don't patch symptoms. WHAT I CAN DO FOR YOU - App Store & TestFlight Releases: signing, provisioning, submission and review issues, including rejections - In-App Purchases & Subscriptions: StoreKit, paywalls, trials, restore purchases, App Store Connect setup - AI Features in iOS Apps: ChatGPT / OpenAI and other AI APIs, plus on-device Core ML and Vision, connected to your app and existing backend - iOS App Development: native iPhone & iPad apps in Swift, SwiftUI and UIKit, from architecture to launch - iOS Bug Fixing & Crash Resolution: crashes, build failures, Xcode and iOS version upgrades - Firebase & REST API Integration: authentication, Firestore, Realtime Database, push notifications, chat, data sync - Hardware & Accessory Companion Apps: iOS apps that connect to external drives and devices, including file transfer, permissions and real-time progress - Flutter App Development: new features, fixes and Flutter upgrades for cross-platform apps - Legacy App Modernization: Objective-C to Swift, UIKit to SwiftUI, step by step without breaking production EXPERIENCE Most of my 11 years were spent inside product teams, building and maintaining apps used by real customers every day. That's why I'm comfortable working in someone else's codebase without breaking what already works. - TapBackup: built the iOS companion app for BMX's Bytesize external drive, from requirements and UI/UX through architecture, native Swift/SwiftUI development and App Store release. One-tap backup of photos, videos, contacts and files to USB storage, with permissions, file management, device connectivity and real-time transfer progress. - Maestro: designed in Figma and built in SwiftUI with Firebase, a native iOS chat app with chatbot selection, conversation lists, onboarding and real-time text and image messaging, taken from concept to the App Store. I also guided the client through the Apple Developer setup. - Walee (influencer marketing & social commerce, 2020-2021): helped build the iOS app from the ground up to App Store release, contributing to architecture and technology decisions alongside the Product Owner, backend and Android teams. Built onboarding, collaborations, referrals, payment UI, push notifications and chat. HOW I WORK 1. I review your code or requirements and tell you honestly what's wrong and what it will take 2.
