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 :)

Independent mobile developer. President of Oxigenic Inc. I make ideas come to life. Let's make yours next.

I’m an iOS and Flutter developer who helps founders, small teams, and businesses fix, finish, and launch mobile apps. I focus on taking apps that are incomplete, broken, rejected, or stuck in development and moving them toward a working release. I’ve worked on App Store submissions, TestFlight builds, SwiftUI apps, Flutter apps, in-app purchases, authentication flows, local data storage, app wrappers, and mobile UI polish. I can help with: • iOS and SwiftUI bug fixes • Flutter app fixes and feature updates • App Store Connect setup and submission support • TestFlight build preparation • App Store rejection review and fixes • In-App Purchases / StoreKit setup and debugging • RevenueCat setup and subscription flow issues • Xcode build errors and runtime debugging • UI cleanup, layout fixes, and mobile polish • Website-to-app wrappers using Capacitor or similar tools • Preparing apps for iOS and Android release My work is practical and release-focused. I don’t overcomplicate projects. I look at what is blocking the app, explain the issue clearly, and help get it fixed so the project can move forward. If your app is stuck, broken, rejected, unfinished, or needs someone to step in and get it ready for launch, I can help.
