👋 Hi, I'm Dwi Prasetyo

Android engineer with 4 years of production experience building offline-first field-worker software in Kotlin. I also build cross-platform apps with Kotlin Multiplatform (Android, iOS, Spring Boot backend).

What I've done at work

• Rebuilt an offline-first outbox sync layer: a 1,731-line monolith became a 56-line orchestrator (91% less code) using Strategy pattern, WorkManager and group-based error isolation, so one failed task no longer blocks the queue.
• Led modularization of a legacy 2017 app from 3 to 40 Gradle modules, with convention plugins for shared build config.
• Co-drove the Java → Kotlin migration (~16% → ~68% Kotlin) and introduced Jetpack Compose.
• The app serves about 1.4K daily active field workers.

How I work I start with simple, explicit solutions (KISS / YAGNI), ship something that works, and let real problems earn their abstractions. Over-engineering on day one is just technical debt with better naming. I care about how an app behaves over time, not just how it looks on day one.

What I'm interested in

• Offline-first architecture (outbox-based sync, deferred execution)
• Predictable state management (MVVM / MVI / reducers)
• Moving business rules out of the UI layer
• Incremental refactoring of long-lived codebases

Side Project

• Yuko-Gamify: KMP productivity app (Android, iOS, Spring Boot) with ~940 automated tests, including pipeline tests on a real SQLDelight stack and 61 "sabotage checks" to prove the tests can fail.

Open source

• Oakane: KMP personal finance app with a shared business layer, Compose and SwiftUI clients.
