What I'm looking for

I’m looking for a backend or product-focused iOS engineering role where I can build high-quality applications using Swift, SwiftUI, and UIKit.

I’m open to remote opportunities and international teams. I’m particularly interested in companies that value clean architecture, code quality, continuous learning, and long-term product development.

I am an iOS Developer with 5 years of commercial experience building and maintaining production mobile applications. Throughout my career, I have worked on social networking, wellness, and utility products, taking features from idea to App Store release.

My primary stack includes Swift, SwiftUI, UIKit, Combine, Core Data, REST APIs, MVVM, and modern iOS architecture. I enjoy designing scalable, maintainable codebases, optimizing performance, and creating smooth user experiences. I’ve also worked with Flutter on cross-platform projects, which has given me a broader understanding of mobile development.
