What I'm looking for

I'm seeking senior roles focused on mobile architecture, cross-platform native integrations, and performance at scale. I enjoy mentoring engineers and driving test-first cultures to ship high-quality mobile experiences.

At Kyivstar.Tech, I worked on My Kyivstar, a flagship app serving 25M+ users across Ukraine. I led its migration to a scalable, clean architecture, speeding feature delivery by ~42%.

I also architected native iOS and Android modules for React Native’s New Architecture and improved app performance through profiling and refactoring. In my current independent work, I’m building a personal mobile project with AI-assisted development workflows and seeking senior roles in mobile architecture, native integrations, and performance.
