I develop modern, high-quality Android applications using Kotlin and Jetpack Compose. I have extensive experience refactoring legacy Java/MVP codebases into modern Kotlin Clean Architecture, and building responsive UIs with Compose.
What I offer:
- Native Android app development using Kotlin and Jetpack Compose
- Legacy Java/MVP to Kotlin Clean Architecture migration
- UI modernization with Jetpack Compose
- Testing with JUnit, Espresso, and Mockito
- Code quality enforcement with SonarQube and standardized project templates
- App Store publishing and compliance
Notable results: I've maintained a production Android app serving 500,000+ monthly active users, achieved a 99.27% bug reduction through rigorous testing protocols, and developed Kompas Harian — a major digital news app for 1 million+ readers. I've also mentored 100+ Android developers as a Subject Matter Expert at Binar Academy.
Tech stack: Kotlin, Jetpack Compose, Java, MVVM, Clean Architecture, JUnit, Espresso, Mockito, Firebase, SonarQube.
