About

I’m an iOS developer with 10 years of experience building and maintaining production mobile apps using Swift, SwiftUI, UIKit, and Objective-C. I’ve led end-to-end delivery across the app lifecycle—feature development, REST API integration, local persistence, App Store releases, performance improvements, and ongoing user-focused support.

Recently, I’ve been expanding my skills through an independent React Native mobile project with backend API integration, while also exploring modern cross-platform architecture and state management. I enjoy using AI-assisted development workflows to accelerate prototyping and learning so I can keep building reliable, polished apps that solve real problems.
