About Me

I'm a mobile developer from Ukraine with 6+ years of experience in hybrid mobile development. Expert in React Native, Expo, TypeScript, and delivering crisp UI/UX with Reanimated.

Strong background in native development — proficient in Java, Kotlin, Swift, and Objective-C for building custom native modules, bridging, and deep platform integration.

Experienced in CI/CD pipelines for mobile apps — from automated builds with GitHub Actions and Fastlane to App Store and Google Play deployments. Driving performance improvements and optimizing development workflows.

Besides work, I'm passionate about open-source and Ukrainian game localization.
