Intro

A developer who sweats the last pixel.

I'm a full-stack developer based in East Java, Indonesia. I care about the whole stack — from data models to the last pixel of an interface.

I spend my time building tools that make development feel lighter, like markupless, a JavaScript framework with implicit reactivity and no build step.

When I'm not coding, I'm configuring my Neovim setup, tinkering with dotfiles, or sketching the next idea.
