iOS developer with 3+ years of experience building scalable, production-ready apps — from new MVPs to complex UIKit-to-SwiftUI migrations. I help founders and product teams ship fast while keeping codebase quality, performance, and long‑term maintainability under control. What I can do for you: • Design and build new iOS apps from scratch (Swift, SwiftUI) • Refactor and migrate legacy UIKit apps to SwiftUI safely and incrementally • Stabilize existing apps: bug fixing, crashes, performance issues, App Store rejection fixes • Implement Clean Architecture, MVVM, VIPER for testable, scalable codebases • Build AI-powered features using Core ML, OpenAI APIs, and custom ML models • Integrate Firebase, REST APIs, and third‑party SDKs (analytics, payments, auth, etc.) • Implement In‑App Purchases and Push Notifications • Handle App Store releases, CI/CD setup, and ongoing maintenance Tech stack: Swift, SwiftUI, UIKit, Combine, async/await Firebase, REST, HTTP/HTTPS, JSON iOS, macOS, watchOS, tvOS Git, GitHub, Jira, Trello Unit testing, XCTest Why clients work with me: • 100% Job Success, Top Rated Plus on Upwork • Fast onboarding, clear communication, and clean, maintainable code • Focus on long‑term architecture, not just “getting it to work” If you need an iOS developer who can quickly plug into your team, improve an existing app, or ship a new AI‑powered product, send me a message and let’s discuss your project.

If you need to resolve some complex iOS-related tasks - you're in the right place! I have experience working both with Swift and Objective-C. Also started creating apps using SwiftUI at 2020. I'm also an expert in the Apple Human Interface Guidelines. As for the architectures, I use the most cutting-edge methodologies such as VIP + Clean Architecture, MVVM+Coordinators, VIPER, MVP. I know how to work on a full-cycle development project since I created different apps from scratch. The most interesting of them were related to: - financial technology + crypto banking; - online shopping solutions; - ARKit + Vision for image recognition and presenting 3d object in AR; - AVFoundation + web sockets for video chats with a remote agent. I also developed an independent SDK in order to be built into different 3rd party apps. For local storage, I usually use Core Data or Realm. For the network layer: Alamofire or native URLSession could be used, it's all up to your preferences and what suits your needs better. In-app purchase with Apple Pay is also a field of my expertise. Feel free to choose different delivery options such as Firebase, Hockey, TestFlight, etc. If you're looking for a developer who really likes his work and is passionate about what he's doing, you've come to the right place! Feel free to contact me anytime you wish. Will be happy to work with you!
