Davi Garcia Aguiar
Senior DevOps Engineer
Davi Garcia Aguiar has spent over 15 years in IT, the last several building and running production cloud infrastructure at scale. As a Senior DevOps Engineer, his day-to-day is Kubernetes, Terraform, and CI/CD pipelines — the discipline of keeping complex systems reliable, observable, and cheap to run. He was part of the team responsible for the cloud infrastructure behind a federal government education platform that brought AI-assisted learning to millions of students across Brazil, with a deliberate focus on reaching low-income youth. Claude is part of his daily toolkit on that same work — reviewing infrastructure code, drafting documentation, and reasoning through incidents before they become outages. This book applies that same instinct — measure first, automate what's proven, keep a human checkpoint on what matters — to the five jobs every founder ends up doing alone.
Jaderson Diego do Nascimento Valdivino
Principal Cloud Specialist
Jaderson Diego do Nascimento Valdivino has 17+ years in IT and holds seven active AWS certifications, including two at the Professional level and the Security Specialty — credentials earned, not collected, across production systems serving millions of users in government, finance, and payments. He was the lead cloud architect for the same federal education platform, where generative AI moved from pilot to production at national scale for low-income students. Claude runs alongside him daily in that work, from architecture reviews to production troubleshooting. His contribution to this book is the same one he brings to every system he runs: a bias for what's provably reliable over what's merely impressive in a demo.
