What I'm looking for

I'm looking to lead high-impact iOS work where I can own architecture, build fluid user experiences, improve reliability and performance, and collaborate closely with product, cloud, and embedded teams.

At Wildberries, I lead architecture and delivery for mission-critical Swift mobile features supporting millions of global users and connected hardware devices while maintaining a 99.9% crash-free session rate. I modernized legacy UIKit code with Clean Architecture, MVVM, dependency injection, and reusable SwiftUI components, reducing front-end development time by 30%.

I've built intuitive iOS products for Alaska Airlines, Actriv Healthcare, EPAM, and ETPGPB, improving retention, engagement, stability, app load time, and offline data performance. My work spans Swift, SwiftUI, UIKit, REST APIs, Core Data, networking, async flows, and responsive iPhone and iPad experiences.

I take ownership from SDK and architecture decisions through CI/CD, testing, debugging, and release quality. I also mentor through code reviews and pair programming, use Instruments for performance tuning, and integrated LLM tooling with YouTrack and the company wiki via MCP to increase delivery throughput by 50%.
