Nathan Brooks is a software engineer and automation practitioner with more than a decade of experience designing, building, and operating infrastructure for technology teams of every size. His career has spanned startups, mid-size product companies, and large enterprises, where he has led DevOps transformations, built cloud-native deployment pipelines, and championed the shift from manual operations to reproducible, version-controlled automation. Along the way he has developed a particular conviction that modern system administration and software engineering are converging fields, and that PowerShell - with its object pipeline and true cross-platform story - is one of the most productive tools available for bridging the two.Beyond day-to-day engineering work, Nathan is a regular contributor to the PowerShell and open-source communities. He has authored modules published to the PowerShell Gallery, filedbug reports and pull requestsagainst widely used libraries, and mentored junior engineers through their first production automation projects. He has spoken at community meetups and developer conferences on topics ranging from infrastructure-as-code to continuous delivery, and he maintains a technical blog where he writes about PowerShell patterns, DevOps practices, and cloud-native design. He holds several industry certifications across Microsoft Azure, Windows Server administration, and DevOps tooling.Hello PowerShell is his attempt to distil years of hands-on experience into a single cohesive volume that any determined reader - whether a sysadmin learning a first programming language or a seasoned developer adding PowerShell to their toolkit - can use to become fluent in the shell that powers so much of modern operations work. When he is not at the keyboard, he is usually reading, travelling, or losing good-natured arguments about whether tabs or spaces make better Indentation.
