The builder behind the work.
Mark Keller is a technology executive, Gulf War veteran, software builder, and author based in Sammamish, Washington.
He spent thirty years inside some of the most demanding engineering organizations in the world, including Amazon and Tendrel, a SaaS startup he co-founded, building platforms, scaling teams, and solving the kind of problems that don’t have a clean answer until someone goes looking for one.
Seven US patents. Engineering organizations built from scratch. Turnarounds at scale. A consistent pattern: given a failing system, find the mechanism underneath it that was missing or broken, and fix that instead of the symptoms.
Paradoxical Logic is the continuation of that work, outside any single company, on problems worth solving, in the form they deserve.
