Top SchoolYevhen Koval is an experienced iOS engineer with 12 years designing and shipping mobile products from startups to enterprise clients, currently building at Zoolatech in Kyiv. He brings deep expertise in Swift and Objective-C, custom UI (Auto Layout, Size Classes, SwiftUI), AVFoundation for complex media workflows, Core Data, multithreading, and in-app purchases. Yevhen has led small teams and served as an engineering manager, balancing hands-on development with delivery practices like MVP-driven iterations and rigorous testing (XCTest, XCUITest, Quick/Nimble).
