Viktor V.

I help startups and product teams build, fix, improve, and release iOS apps — from first prototype to App Store release. I specialize in Swift, SwiftUI, UIKit, StoreKit, subscriptions, Firebase, and maintaining existing iOS codebases. I have 8+ years of commercial iOS experience and have worked on 15+ apps, including VPN apps, utility apps, AI apps, ad blockers, and subscription-based products. What I can help with: • Build iOS apps from scratch • Improve or maintain existing iOS apps • Fix crashes, bugs, and performance issues • Add subscriptions and in-app purchases • Integrate Firebase, AppsFlyer, Adapty, RevenueCat, or other SDKs • Prepare and release apps to the App Store • Migrate Objective-C code to Swift • Improve architecture and clean up legacy code My main stack: Swift, SwiftUI, UIKit, Objective-C, StoreKit 2, Firebase, REST API, Push Notifications, App Store Connect, Xcode, Combine, Core Data. I am comfortable taking ownership of features, working with existing codebases, and communicating clearly during the project. If you need a reliable iOS developer who can not only write code, but also help you ship and improve your product, I can help.
