Rockstar🎓
Top SchoolWilliam Hopper is a senior software engineer in Portland with 14 years of experience building developer-focused infrastructure, CI backends, and cloud platforms across Ruby, Rust, Go, PHP, and Puppet. He combines hands-on engineering with facilitator and mentorship roles—leading an engineering-wide mentorship program at GitHub and previously acting as a Scrum Master and technical lead at Acquia. His background spans the full development lifecycle from release engineering and on-call incident response to modernizing large-scale automation (notably contributions to the widely used puppet project and its packaging/tests).

The user also removed several deprecated parameters and methods, as well as legacy code such as MSI providers and stringify facts.
