Summary
👤
Senior🎓
Top SchoolOleksandr Denysyuk is an iOS developer with over 5 years focused on Swift (and a background in Objective-C) who builds production-grade apps across startups and enterprise projects from Vancouver, WA. He has deep hands-on experience with SwiftUI, Combine, MVVM/MVC architectures, Core Data/Realm/SQLite, ARKit/3D scanning, and multimedia features like custom video players and YouTube integration. His portfolio spans end-to-end projects—creating apps from scratch, refactoring large legacy codebases into modular frameworks, and leading small teams while owning code quality and documentation. Notable for shipping complex features such as AR room scanning, custom map clustering, Bluetooth data transfer, and robust auth/payment flows, he favors minimal dependencies and clean, maintainable code. A quick learner and permanent resident in the U.S., he pairs pragmatism with curiosity, often implementing novel technical approaches (three different AR scanning methods) to solve product needs.
