02 / THE PRACTICESMALL BY DESIGN. END-TO-END BY NATURE.

One mind.
Many disciplines.

I’m Kurt Kurniawan Febri, an independent engineer based in Jakarta. I work at the intersection of product, code, and the infrastructure that makes it all run.

I believe good software brings clarity. To a complicated process. To a busy team. To an idea that hasn’t quite found its shape. My practice connects careful design with practical engineering, from architecture through launch.
