Senior iOS Enginner | Swift | SwfitUI | Objective CViktor Zahurskyi
I build high-performance, native iOS apps using Swift, SwiftUI, and Objective-C, pairing clean architecture with pixel-perfect design. I specialize in scalable MVVM/async-await patterns, secure API integrations, and offline-first data layers for reliability and speed. With XCTest, Fastlane, and TestFlight CI/CD, I deliver smooth 60fps experiences that are App Store–ready. Whether it’s a new build or a rescue of an existing codebase, I onboard fast and ship measurable results.
What's included
Native iOS App Development
A fully functional Swift or SwiftUI app developed natively for iPhone and iPad, designed for speed, stability, and long‑term scalability — following Apple’s Human Interface Guidelines.
UI/UX Design Integration
Clean, responsive design implementation built from Figma or XD prototypes, ensuring flawless transitions, accessibility, and pixel‑perfect layouts across iOS devices.
Backend Integration
Seamless connection with RESTful APIs, Firebase, or custom endpoints, allowing smooth data flow, authentication, and real‑time updates within the app environment.
Local & Cloud Data Management
Setup of Core Data, Realm, or CloudKit for offline access, cloud sync, and secure data handling that keeps user experiences consistent — even without connectivity.
Testing & Quality Assurance
Comprehensive testing across devices and iOS versions using XCTest, TestFlight, and manual review to guarantee stable performance and a bug‑free release.
App Store Deployment
Complete guidance and support through App Store submission, including provisioning profiles, signing configurations, metadata setup, and review preparation.
FAQs
I focus exclusively on native iOS development using Swift and SwiftUI, ensuring optimal performance, seamless animations, and integration with Apple’s latest frameworks.
Yes. I can either collaborate with your designer or translate your Figma/XD designs into high‑quality native interfaces. I also offer assistance in refining UI/UX for a truly Apple‑native look and feel.
Absolutely. All apps are built with responsive layouts and adaptive design principles to work flawlessly across multiple devices and orientations.
Yes. I integrate RESTful APIs, Firebase, or custom endpoints to power features such as authentication, data sync, and live content updates directly within the app.
Yes. You’ll have full ownership of the source code, assets, and documentation. Everything is delivered through a private Git repository or your preferred version-control platform.
Yes. I can embed AI‑powered components (ChatGPT, Core ML, or custom APIs) and connect automations using n8n or Make.com, enabling intelligent behaviors and backend workflows directly within your iOS app.
