About this gig

Are you looking for a fast, reliable developer to bring your mobile app idea to life? I specialize in building high-quality, cross-platform apps using React Native and Expo one codebase, running smoothly on both Android and iOS.

I recently published my own app, NoteVerse (a modern note-taking app), on Google Play so I know firsthand what it takes to go from idea to a real, working product on the store.

What I can build for you:

  • Custom mobile apps from scratch (React Native + Expo)
  • UI/UX implementation from Figma or reference designs
  • Integration with APIs, Firebase, AdMob, push notifications, and more
  • Bug fixes and improvements to existing React Native apps
  • Publishing support for Google Play / App Store

Why work with me:

  • Clean, maintainable code
  • Clear communication throughout the project
  • Real experience shipping an app to production

Send me a message with your project details, and let's build something great together!

I'm a mobile app developer specialized in React Native and Expo, building Android apps from scratch — from UI design and architecture to publishing on Google Play. As an example of my work, I recently launched NoteVerse, a note-taking app on the Play Store, where I handled everything from development to monetization (AdMob integration). I can help with a wide range of mobile app projects: building new apps from an idea, improving or adding features to existing apps, fixing bugs, or optimizing performance. I focus on clean, functional results and clear communication throughout the project.
