About me

A quick glimpse of who I am beyond the keyboard.

📱

Android craftsman

I build delightful mobile experiences at scale, with a soft spot for clean architecture, storage APIs, and developer tooling.

🌞

Cheerful & warm

I believe good vibes ship better code. Expect emojis, honest feedback, and a friendly hello every morning.

📸

Explorer at heart

Traveling, photography, nature walks, a good game, and the latest gadgets. That's my weekend recharge recipe.

Expertise

The stacks I reach for when shipping products.

Kotlin

My daily driver for production Android — coroutines, flows, and clean architecture.
Java

Years of battle-tested Android experience, from legacy SDKs to library maintenance.
Flutter

Cross-platform UIs that stay fast and pixel-perfect on both iOS and Android.
Compose Multiplatform

Sharing Kotlin UI across Android, iOS, desktop and web with a single codebase.

My journey

Where I've shipped code and grown as an engineer.

Present
GTF · GoPay

Currently building payment experiences for millions at GoTo Financial (GoPay) as an Android engineer.
3 years
DANA

My very first job — contributed for three years at DANA, one of Indonesia's leading e-wallets. Learned, shipped, and grew a ton.
