Let's talk.

Open to Android roles, smart-contract work, and collaborations. Email is the fastest route; I usually reply within a day.

Before you write

A few answers that might save us both a round trip.

What Android work are you doing right now?

Checkout, payment and authorization features for an Indomaret POS built in Kotlin and Compose, planned for phased rollout across 24,351 stores. Alongside it I ship field-operations apps — QR documents, WiFi-paired queue displays streaming over WebSocket, and alarm monitoring.

Do you take on smart-contract work?

Yes. I write Solidity with Foundry and Hardhat, and I have shipped escrow contracts plus a TypeScript SDK for an x402 payment rail on Mantle. I am comfortable with on-chain payouts, registries, and agent workflows.

What's the story behind the batik paper?

It started as a final-year research project, fine-tuning ResNet-50 on four Keraton batik motif classes. The model reached 97.8% test accuracy, and the paper was published in AITI volume 23.
