About

I have extensive experience in iOS development, working with technologies like Swift, SwiftUI, MVVM, Combine, and RxSwift. As part of a 20+ developer team, I owned the FitAnalytics feature, improved test coverage, and maintained the codebase. My responsibilities included integrating new unit/UI tests, supporting and improving features, and mentoring junior developers. At Mellow App, I architected iOS and WatchOS applications from scratch, designing them with the latest SwiftUI features, though the project was ultimately closed due to Apple's policy restrictions. At Optherium Labs, I contributed to a B2B white-label neo banking solution, utilizing a tech stack that included Swift, VIPER, and Kotlin. My duties involved UI testing with Selenium, test automation using CI/DI and Python, and adding new features. In the Priority Lab project, I enhanced app stability and transitioned from Objective-C to Swift. Leading a small team at HoozAround, I migrated projects from Objective-C to Swift and implemented features for location tracking and user movements. At HiBye, I was the sole iOS developer, working extensively with map APIs and developing user authentication flows. I hold a Bachelor’s degree in Cybersecurity from Lviv Polytechnic National University.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
