Nika K.

I build and rescue mobile apps that ship — 12+ years in native iOS (Swift, SwiftUI, UIKit) and 4+ years in Flutter, with production apps in fintech, gambling, crypto, and transit. What makes me different from most Flutter developers: I shipped native first. Platform channels, native modules, App Store review quirks, performance profiling — the places where Flutter-only developers get stuck are where I'm strongest. RECENT WORK: Architected a Flutter gambling app from scratch (BLoC, multiple payment gateway integrations, Firebase) for iOS and Android Led an iOS chapter of 7 engineers at one of Georgia's largest banks — SwiftUI at scale, MVVM+Coordinator architecture, modular 2FA system Built and shipped a real-time transit app for the City of Ottawa to both the App Store and Google Play from a single Flutter codebase Developed a crypto wallet with NFT ticketing, Web3 logins, and biometric authentication Maintained and hardened a high-load iOS betting app for a major UK gambling brand WHERE I'M MOST VALUABLE: Flutter apps that need to feel truly native on iOS Migrating native iOS/Android apps to Flutter or Kotlin Multiplatform Rescuing troubled codebases — clean architecture, testing, CI/CD (Fastlane, GitHub Actions, Bitrise) Launch-phase work: stabilization, performance, App Store submission and review
