Hi! I'm Vladyslav - an iOS engineer with 12+ years of experience building apps people rely on every day. I currently work at TabTrader BV, where I develop a high-performance cryptocurrency trading platform used by over 500 000 people. In parallel, I serve as CTO at Your Accessible Flight, an accessibility-focused travel startup.
My core expertise spans Swift and SwiftUI, fintech charting engines (Core Graphics, Metal), BLE/IoT hardware integration, and Swift Concurrency. I care deeply about architecture - MVVM, Clean Architecture, and testable code - and I've led teams as well as shipped solo.
Outside of engineering, I'm into music, artificial intelligence, and robotics. I find that cross-disciplinary curiosity makes for better software.
