From the help desk
to IT leadership.

This desk in Bothell is where the story ends. It starts in 2010 at a Tempe help desk: eight jobs, each one’s everyday work drawn in the world of a different Studio Ghibli film.

    Working across Microsoft 365, Entra ID, Okta, Google Workspace, Intune, Zscaler, Zendesk, Jira, PowerShell, TypeScript, React, Python, and Microsoft Graph API.

    The Workbench.

    Every job left something on the desk. Four results from the day job, six side projects, and one bonus. Turn the pages, or .
