Code withcharacter.

I'm a software engineer in Bandung building fast, accessible interfaces that don't take themselves too seriously. Currently focused on design systems and the small details people feel but never notice.

01 / About

A developer who sweats the last four pixels.

Part engineer, part design nerd. I care about how interfaces work, how they feel, and how quickly they get out of the way.

I sit in the space between engineering and design — close enough to the code to care about bundle sizes, close enough to the canvas to care about the last four pixels. For the past six years I've helped product teams turn fuzzy ideas into interfaces that feel obvious.

These days I lead frontend at a small product studio, maintain a design system used by four squads, and spend my evenings making pixel art and questionable side projects.

“Good interfaces feel obvious. Getting there is anything but.”

— my design philosophy, probably
