I’m a Senior iOS Engineer with 11+ years of experience building and scaling consumer mobile products. At QIWI, I worked on QIWI Wallet across payments, onboarding, authentication, and core product journeys using Swift, Objective-C, UIKit, and modern iOS technologies.
I redesigned registration and authentication around a backend state machine and introduced percentage-based rollout, increasing registration conversion by 5%, reducing completion time by 20%, and cutting SMS costs by about 5%.
I shipped Apple Pay in-app provisioning, built Backend-Driven UI for payment forms, introduced a company-wide mobile design system, and developed the deep link and Universal Links platform used across product and marketing flows. I also implemented SSL pinning with certificate rotation and modularized the application to improve build times and development scalability.
On the engineering productivity side, I built a continuous delivery pipeline with Fastlane and TeamCity, including automated testing and App Store release workflows. I also mentored engineers from backend, QA, and Android into iOS development and launched an internship program at QIWI.
Outside of my main work, I have shipped several independent apps to the App Store and won and placed in multiple hackathons, including a sponsor prize at TechCrunch San Francisco.
