Hi, everyone! 👋

I'm a Senior Flutter Engineer based in Indonesia, with 8+ years in software development and Flutter as my main stack since 2019. I also work in native Kotlin and Swift and in React Native, and I've done web work in Next.js with some backend fixes in Go.

I led the Flutter migration of Teman Bumil, replacing its separate native Android and iOS codebases with one app (1M+ downloads, 150K MAU, 99.5% crash-free sessions). At Bosshire I built the Flutter job portal from concept to launch (10K+ downloads, 2.5K MAU, 4.8/5 rating on Google Play and the App Store).

I mostly work with Clean Architecture, BLoC/Cubit, unit tests, and TDD on business logic. Claude Code is part of my daily workflow, and it helped increase release velocity by 30% at Bosshire. I like digging into production issues with Crashlytics and Flutter DevTools.

I led a squad of 5 mobile engineers, then managed a 24-person product engineering team as Technology Manager. At Bosshire I led an 8-person cross-functional team and was also its only mobile engineer.

My open-source Flutter Enterprise Starter Kit has 50+ GitHub stars. I'm open to remote roles with global teams.
