Marian Montagnino is a software engineer and educator focused on the production craft of building command-line interfaces, particularly in Go.
Her CourseFlix listing carries The Art of Command Line Interfaces — a structured treatment of CLI design: the user-experience patterns, the argument-parsing decisions, the output formatting patterns, the publishing workflow, and the engineering patterns that distinguish polished CLI tools from generic command-line scripts.
Material is paid and aimed at developers ready to ship CLI tools as a deliberate product category. For broader content, see CourseFlix's Golang category page.
