Rangga Danu Kusuma

Full-Stack Developer / Game developer

I build fast, accessible web products — from database schema to pixel-perfect UI.

About

I've spent the last 4 years turning ambiguous product ideas into shipped software.

I'm a full-stack developer focused on developer tools and internal platforms. I like small teams, fast feedback loops, and code that's easy to delete.
