App Store Specialist | Senior iOS Engineer | Base44 | Lovable | Replit

Built an app in Base44, Lovable, Replit or another AI builder and stuck at the App Store? I can get it approved, end to end, from native wrapping and code signing to TestFlight and Apple review compliance. But that is just one side of what I do. With 7+ years of professional iOS development experience and a 100% Job Success Score, I build and ship full-scale iOS apps from scratch using Swift, SwiftUI, and UIKit. Fast, clean, and App Store ready from day one. My expertise includes: - Base44 & AI-built app publishing: End to end App Store submission under your own developer account - App Store compliance & rejection rescue: Resolving Guideline 4.2, 4.3, and other rejections - SwiftUI & UIKit development: Building modern, scalable, and production-ready iOS apps - Bug fixing & performance optimization: Improving stability, speed, and memory efficiency - API & third-party SDK integration: Firebase, RevenueCat, push notifications, in-app purchases - Long-term support & team collaboration: A reliable iOS expert on call when you need one What sets me apart is that I understand both sides of the equation. I know how AI builders work and I know exactly what Apple expects. That means fewer rejections, faster approvals, and no surprises. Whether you need a new iOS app built from scratch, want your AI-generated app published to the App Store, or need an experienced engineer to rescue a rejected submission, I deliver on time with clear communication throughout. Let's talk and get your app live :)
