Summary
🤩
Rockstar🎓
Top SchoolLeonid Liadveikin is an experienced iOS developer with over a decade in software engineering and 8+ years focused on UIKit alongside 4+ years building SwiftUI-first interfaces. He has shipped apps across iOS, watchOS, tvOS and visionOS, and has hands-on cross-platform experience with KMM, Flutter, Ionic, Tizen and Android, plus backend work in Spring and Vapor. Leonid repeatedly leads refactors from Objective-C/ReactiveSwift to modern Swift, SwiftConcurrency and SwiftData, and has driven CI/CD, testing and Metal migrations in large teams. He brings a low-level curiosity—working with Metal, microcontrollers for IoT and even home router tinkering—that informs pragmatic, performance-aware mobile engineering. Based in Vienna, he’s comfortable as the sole iOS engineer or as part of 50+ developer organizations, and he actively experiments with new platforms and design systems.
