Yurii B.

Senior iOS Engineer (5+ yrs) | Swift, SwiftUI, UIKit | Mobile apps used by 100k+ people Mobile developer with 5+ years shipping production iOS apps across navigation, fintech, wellness, and AR — including a mobile app used by 100,000+ people across 42 languages (WiFi Map, 4.9★). What I bring to mobile projects: — Reduced mobile app load times by 35% through systematic profiling and optimization — Cut production issues 40% by building out crash reporting and monitoring pipelines — Full-cycle ownership: architecture → build → App Store submission → post-launch stability — Clean, testable mobile codebases (MVVM, Clean Architecture, TDD) that stay maintainable long after launch — not just at handoff.
