PowerShell Administration & Automation Suite

A library of scripts that turned Active Directory and M365 admin from a full-time chore into a scheduled task.

Private — built in an employer environment, details on request↓ significant Manual overhead

The problem

High-volume administrative work — AD reporting, bulk account lifecycle changes, license provisioning — was eating time a 3-person team didn't have to spare.

The solution

I architected and deployed a suite of custom PowerShell scripts covering Active Directory reporting, bulk user account lifecycle management, and Microsoft 365 license provisioning, replacing manual, click-through admin work with repeatable, scheduled automation.

Impact

  • Dramatically reduced manual administrative overhead
  • Freed the team to focus on complex technical issues instead of repetitive maintenance
  • Reduced the chance of human error in bulk account operations

How it works

Architecture / Flow
01AD + M365 admin modules authenticate via service accounts / app registrations
02Reporting scripts run on a schedule and output to a shared dashboard/export
03Lifecycle scripts handle onboarding, offboarding, and bulk changes from a single source list
04License provisioning scripts reconcile assigned vs. required licenses automatically

Lessons learned

  • Idempotent scripts save you from yourself — every script was built to be safely re-run.
  • Logging and dry-run modes aren't optional when a script touches bulk account changes.
  • Small automations compound: reporting scripts fed the data that made the trend-analysis project possible.
