powershellengineer.comAbout
Built on nights and weekends
I am a K-12 Director of Technology in southwest Michigan and the Chief Technology Officer of Model Communicator, a free augmentative and alternative communication system for anyone who needs one.
Twenty years in IT, two Microsoft MVP awards for PowerShell, and one book, PowerShell for Systems Engineers, written for admins who need automation that works in production, not a reference manual.
Everything on this site is my own work, built on my own time and my own equipment, and shared because school IT runs on budgets that do not stretch to enterprise anything. The guides are plain-language checklists written so any district can pick them up and use them.
Communication is a right, not a privilege. Model Communicator exists to remove the barriers between a person and the words they need.
The idea behind Model Communicator
Speaking
Field reports, not slide decks
No vendor pitches. Real talk from someone who responds to incidents at 11pm and ships tools on weekends. Every talk comes with a handout you can take back to your district.

Zero Trust Security

Just Jim. No sales funnel.
I answer every email personally. Districts and organizations hire me for Google Workspace and Microsoft 365 hardening, Active Directory security reviews, PowerShell automation, and AAC program implementation. If you just want to pick my brain for 30 minutes, that works too.
