Hi, I’m Anton Kryuchykau. I’m a senior iOS developer with 10+ years of delivering mobile applications for healthcare, telecom, and social networking. I specialize in Swift, SwiftUI, UIKit, and Combine, with strong skills in performance optimization, REST API integration, and App Store release management. I enjoy building reliable, scalable software and collaborating with designers, QA, and stakeholders to ship solid experiences.
I’ve led a 5-person iOS team, improved delivery velocity through structured code reviews and documentation, and contributed to large-scale products such as Viber (1B+ users) and healthcare platforms. I’m passionate about clean architecture, modular design, and maintaining a top-notch user experience across platforms and releases.
