I’m an experienced iOS Developer who helps businesses build, improve, and scale high-quality iOS applications. I specialize in turning ideas and existing products into stable, user-friendly, and performance-optimized apps ready for real users. I’ve worked on production iOS applications, including marketplace and service-based apps, where I was responsible for feature development, UI/UX improvements, bug fixing, and long-term app maintenance. I focus not only on clean code, but also on business goals: stability, retention, and smooth user experience. What I can help you with: • iOS app development using Swift, SwiftUI, UIKit • New features and app enhancements • Bug fixing, refactoring, and performance optimization • App Store-ready builds and long-term maintenance • Improving existing apps (even if codebase is legacy) I’m reliable, detail-oriented, and easy to communicate with. If you’re looking for an iOS developer who can quickly understand your product and deliver real value — let’s talk.
