At AlephLabs, I build and maintain React.js admin consoles for motorcycle workshops across Indonesia and a banking partner’s financial tool. I’ve also worked on a healthcare app connecting patients and healthcare professionals.

At AlephLabs, I created interactive event displays connected to LED displays using NFC, WebSocket, and web browsers. I also built proof-of-concepts for a hotel activity recommendation engine and an eKYC web app.

Alongside frontend development, I build interactive installations with Arduino, ESP32, and Raspberry Pi. My commissioned projects include a 24-node fiber optic installation for Art Jakarta and control systems for kinetic installations.
