About

A short narrative. Scroll through the timeline to trace the journey.

I'm Nicolas Walker — a builder, researcher, and technologist. I spend my time between Rio de Janeiro, New York, and Zurich, working at the intersection of design, technology, and human systems.

I'm drawn to hard problems: privacy infrastructure, autonomous agents, simulation design, and the question of how technology can serve people without exploiting them. My approach is rooted in first-principles thinking, rapid experimentation, and a healthy distrust of conventional wisdom.
