Lead Android Developer at Tuntun Sekuritas · indie game maker at Spike Code Labs

About

In short

I'm an Android engineer with eight years in the platform and a software career that started in 2016, now leading Android at Tuntun Sekuritas Indonesia. I work in Kotlin and Jetpack Compose, have twice helped move a large app onto clean architecture, and keep a close eye on what Firebase Crashlytics has to say.

Before Tuntun I built investment-discovery features at Stockbit and owned the doctor-consultation chat flow at Alodokter. I started out in 2016 as a software engineer at a US-based company in Jakarta and committed to Android full-time in 2018.

On the side I run Spike Code Labs, where I design and ship Ceritain and Arush end to end — client, API, store listing and support email.

Open to new opportunities in Android engineering, and to contract work on Android, iOS and Node backends.
