ABOUT ME
iOS/macOS Tech Lead, Swift language teacher
iOS/macOS Tech Lead, Swift language teacher
Senior iOS/macOS Developer with 15+ years of experience in mobile and
desktop app development for Apple platforms. I was leading a digital
transformation of a neobank application in Credit Dnipro bank. In
addition, I have skills in integration of hardware with iOS and
connectivity. Actively implementing different AI models in iOS, as well as
MCP and Agentic workflows. Having advanced knowledge of UI/UX design
and tools, like Photoshop and Figma, and being a graphic designer in the
past, helped to shape the look and feel of products. Published myself
numerous apps on the AppStore and negotiated rejections with Apple
review team. Have minimal knowledge of Android, enough to make minor
fixes and lead cross-platform development.
Creator of Threat Explorer, a unique penetration testing tool for finding
security vulnerabilities in iOS and macOS applications. Proficient in
Swift, Objective-C, SwiftUI, and advanced technologies like MetalKit,
CoreML, and ARKit.
