06 / HUMAN IN THE LOOP

BEYOND THE TERMINAL

A dad.A gamer.Still curious.

I’m a dad to a little girl, a lifelong gamer and a collector of physical games. I like systems, stories, teaching — and people who genuinely care about what they make.

01PerspectiveFatherhood made time, patience and what matters feel very concrete.

02PlayGames shaped my taste for systems, feedback loops and worlds worth exploring.

The best products feel considered by actual humans.
