About this gig

With 15+ years of professional software development experience, I have built dozens of Android apps in Kotlin and Java, from idea to launch. I deliver production software across mobile, backend, and desktop, and several of my own apps are live on Google Play, so you can see my work first-hand.


What I can do for you:

- Build a new Android app from scratch (Kotlin or Java)

- Add new features to your existing app

- Fix bugs, crashes, and performance issues

- Integrate REST APIs, Firebase, and local storage (Room/SQLite)

- Prepare and publish your app to Google Play


Why work with me:

- 15+ years of experience and dozens of Android apps delivered

- Production apps live on Google Play

- Clear, honest communication. I tell you upfront what is realistic

- Clean, maintainable code, and you work directly with the developer
