He is the founder of Cloud War Game, a live incident response simulation platform and the creator of the Zero to Hero on AWS Security animated course. His current passion project is Tech Debt, a rogue-lite base-builder strategy game where players must research tech, level up their engineering team, and keep servers running while fending off real-world cyberattacks like XSS, SQL injections, and DDoS. Whether through consulting, speaking engagements, or game design, Matt empowers technical leaders to ensure their systems are fast, secure, and ready to scale.
