EXPERIENCE

Nitrix — iOS Developer Feb 2024 – Present
Streaming application for iOS and tvOS: a built-in player for m3u playlists covering movies, TV shows and live TV, with Chromecast,
subtitles and offline viewing. Team of 3 developers, ~1.6M monthly active users.
• Migrated 20+ screens from UIKit to SwiftUI over six months and completed the transition, improving UI performance, crash
rates and animation quality.
• Built the offline download manager — queued background downloads, storage management and offline playback.
• Implemented multi-window live channel viewing, allowing several streams to be played and controlled simultaneously.
• Own the tvOS build end to end, including focus engine behaviour across custom layouts and RTL localization of the interface.
• Raised unit test coverage to 83% (XCTest) and keep crash-free sessions at 99.5–99.8% across a 1.6M MAU user base.
• Write new code with Swift Concurrency (async/await, actors) while maintaining existing Combine-based modules.

speaker sessions.
• Built the iOS application from scratch and owned all architecture decisions, choosing MVVM-C and SwiftData for the project.
• Led iOS development in a volunteer team with continuous turnover — onboarded new contributors, decomposed and
estimated work, reviewed code and kept delivery on track without formal authority or budget.
• Worked directly with the organization's stakeholders to turn programme requirements into scope.
• Set up the CI/CD pipeline with Fastlane and GitHub Actions for automated builds and TestFlight distribution.
• Delivered the application feature-complete; release was pending on the organization's side when I left.

turnaround.

PROJECTS

ТРАСА: тести ПДР 2026 — Solo Developer, own product Jul 2026 – Present
Driving-theory exam prep app published under my own developer account, rated 5.0 in the App Store Education category.
• Designed, built and shipped the app on my own, from concept to App Store release.
• Implemented the official exam format (20 questions, 20 minutes, two-error limit) and topic-by-topic practice that resumes
where the user stopped.
• Built a mistakes-review mode, profile statistics, achievements and a daily study streak.
• Combined rewarded ads with in-app purchases — users unlock lessons by watching an ad, or buy attempt packs or lifetime
access.
• Added Sign in with Apple and Google sign-in, and shipped two updates in the first two weeks in response to reviews.

FEMO: Pelvic Floor Exercises · Kegel Pro: Men's Health — Primary iOS Developer Jun 2025 – Jun 2026
Two subscription-based pelvic floor training apps in the App Store Medical category, built for the same client. Primary developer on
both, with one collaborator.
• Built both apps in SwiftUI and SwiftData with a modular MVVM structure — guided workout sessions, progress statistics,
article content and settings across ~9k lines of Swift.
• Implemented the web-to-app subscription flow: resolved deferred deeplink data on first install, linked the purchase profile to
the web checkout provider and restored the entitlement in-app, persisting the user identifier in Keychain so premium
survives reinstalls.
• Built the onboarding quiz with personalized plan generation, and paywalls on StoreKit 2 (purchase, restore, entitlement
checks) with Adapty for remote paywall configuration and A/B testing.
• Localized both apps into 13 languages using String Catalogs, including RTL support for Arabic.
• Added a type-safe analytics event layer over Firebase Analytics, plus Crashlytics and FCM push notifications.
• Implemented local notification reminders scheduled per weekday and time.
• Adapted the existing codebase to launch the second product for a different audience in two weeks.
• Shipped FEMO in Sep 2025 and maintained it through seven App Store releases.
