Introduction

Byron Arnao

Principal Technologist · Global Responsible AI Lead, AWS

"It started with one question — could I actually talk to my dog?"

Byron builds things to find out what they're really capable of — a curiosity that pulled him from two decades in banking into the frontier of emerging technology. By day he leads responsible AI across one of the world's largest hyperscalers; by night he runs a five-agent AI fleet and two labs that pressure-test what agents really do. Off-keyboard: triathlete and marathoner, J/24 sailboat racer, mountain and canyon climber, Smithsonian-published photographer, husband and father. Former Glen Rock, NJ councilman. Fifty-plus countries.
