About me
I'm an iOS developer from Ukraine, 5+ years with Swift. I ship native apps end to end: SwiftUI and UIKIt interfaces, clean MVVM code, in-app purchases with StoreKit 2, API and AI integrations, and App Store submission. I've published my own apps, so I've been on both sides — writing the code and dealing with review rejections, crash reports and paywall conversion. What you get from me: clear communication in English, no disappearing mid-project, and an honest "this won't work" when that's the truth. Message me before ordering and I'll tell you exactly what your project needs.... Read more

Self Employed • Full-time

Jun 2021 - Present • 5 yrs 2 mos

Independent iOS developer building and shipping native apps end to end — from first sketch to App Store release. SHIPPED PRODUCTS Several native iOS apps published on the App Store, including AI-powered utilities and subscription-based consumer products. Details available on request, subject to NDA. WHAT I DO - Native iOS development in Swift, SwiftUI and UIKit - AI API integration: ChatGPT, Gemini, DeepL, speech and camera features - Subscriptions and in-app purchases with StoreKit 2 and RevenueCat - Backend work with REST APIs, Firebase, CoreData and SwiftData - MVVM architecture, refactoring and modernizing legacy projects - App Store Connect setup, submission and review support - App Store Optimization — keyword research, metadata and screenshots Because I run my own apps, I handle the parts most developers skip: pricing and paywall logic, store metadata, review rejections and post-launch iteration. I write code that another developer can pick up later, and I tell clients honestly when a smaller scope would serve them better.
