Hey, I'm Aldy.

I enjoy turning complex problems into simple, usable experiences. I've helped Ruangguru, Schoters, and Recharge build better products, and many more companies along the way. These days I'm building crypto trading interfaces at Pintu, and sharing what I learn along the way.

Lately I've been building a few things on the side. ariva.id is a tryout platform for CPNS and BUMN prep in Indonesia. And getkeyboo.app brings mechanical iOS keyboard sounds to macOS — coming soon.

Writing:

Reading the Duolingo Handbook as a Software Engineer
How We Keep Crypto Apps Fast Under High-Frequency Updates
My Experience as a Frontend Engineer in Crypto
What I've Learned About Under vs Over Engineering
The Problem With 'Hey, Got a Sec?'
Displaying Images Correctly on Your Website

Good design begins with curiosity. Outside building, I share what I'm learning on X, open-source on GitHub, and connect with other builders on LinkedIn.
