It all started with building a site in 2012, now I design for teams across Asia, Europe, and the US.

My name is David. I'm Indonesian, based in Germany, and I've spent 7+ years designing digital products for startups, agencies, and enterprises, mostly in social media, e-commerce, and complex B2B tools. I enjoy learning, building what I'm passionate about, and experimenting with AI, comedy, and photography.

I built my first WordPress site in 2012 for a class project (see it here).

This portfolio is built with Next.js and Tailwind CSS.

It's also an AI-native build. The design system, copy, and motion were co-created with AI, and the code was written with AI assistance using Claude, VS Code, and Opencode.

Special thanks to everyone who reviewed this site, and to all the amazing friends and colleagues who've shaped my journey along the way.
