I build cross-platform mobile apps using Expo and React Native. I created and deployed some apps to the Play Store, developing features focused on user journey and usability. I can develop new apps, improve existing ones, fix bugs, refactor code, and implement high-quality UI components. My approach focuses on performance, stability, and excellent UX. Whether you need MVPs, business apps, customer portals, or app extensions for web platforms, I deliver production-ready solutions with clear documentation and continuous improvement.
