About the author

Applied operations research scientist with over a decade of experience designing and deploying large-scale optimization and simulation systems in production environments. Former D1 student-athlete — who grew up on Detroit's East Side, on 8 Mile Road — turned mathematician turned decision scientist, with a contrarian, practitioner-first approach to decisions under uncertainty.

Expertise in mixed-integer programming, stochastic modeling, decomposition methods, and algorithm design for supply chain and logistics applications. Not interested in models that live in notebooks — only systems that ship and drive real outcomes.

Led end-to-end development of decision systems impacting $60B+ in annual planning decisions, including production planning, vehicle routing, scheduling, and demand-supply matching.

Co-founder of Bit Bros LLC with John Elam, where I author books, consult on decision intelligence, and design career programs for the next generation of data professionals. Former Data Content Lead at LeetCode, and advising a stealth startup in the optimization space.

Reviews

[Jonathon Richards]

A smart and genuinely engaging way to explore decision-making under uncertainty. The novel format makes the ideas easier to absorb without watering them down, and the lessons feel practical rather than academic.

A fast, useful read for anyone who has to make important decisions without having perfect information.
