CURIOSITY · CRAFT · COMPUTING

1998 — 2004

The origin story

From art school to low-level systems

A background in music and visual art met an early obsession with computers. By 2004, that curiosity had become a prize-winning graphical environment for MS-DOS.

  • First place at the Mureș Cup in 2004
  • Built a window manager, mouse support and audio player
  • Mixed visual craft with low-level engineering
8086 AssemblyPascalVESASoundBlasterMS-DOS

THE THROUGHLINE

Curious since the first line of code.

Before the trading platforms, design systems and data infrastructure, there was music, visual art and a home-built MS-DOS interface. Nearly 30 years later, the instinct is unchanged: understand the system, improve the craft, and help the people around it do their best work.
