What I'm looking for

I am seeking senior iOS roles on collaborative, fast-paced teams where I can lead mobile development, adopt new tech, and drive product impact.

I am a senior iOS developer with over seven years of professional experience building mobile applications across startups and enterprise clients. I specialize in delivering high-quality, maintainable code and contributing to both new products and existing codebases.

I have led development on apps using Swift, Objective-C, and common iOS frameworks, integrating real-time communication (Agora), video streaming (Amazon IVS), Firebase, and various networking and persistence libraries. My projects include social, wellness, logistics, and enterprise health applications with App Store releases.

I embrace modern architectures and patterns such as MVC, MVVM, VIPER, RxSwift, and Clean Architecture, and I focus on performance, security, and user experience—achieving measurable improvements like a 20% increase in engagement for one project.

I thrive in fast-paced, startup-like environments where I can wear multiple hats, collaborate across international teams, and continuously adopt new technologies to maximize development efficiency.
