Selected work

Projects that improved day-to-day IT.

Independent project

CIS Mini RMM as applied learning.

Outside my employment history, I built a private endpoint-management system for CIS Solutions Group. It brings together a Windows Agent and watchdog Auditor, an ASP.NET Core API, PostgreSQL, a restricted agent gateway, and signed software updates.

The value for this résumé is the breadth of work behind it: Windows services, authentication, databases, release processes, troubleshooting, and security decisions.

PROJECT / IMPLEMENTED

From endpoint to administrator

  1. Enroll a device with a one-time token.
  2. Report health and version information through an outbound Agent connection.
  3. Recover the Agent with a separate Auditor service.
  4. Verify signed releases before updating.

This is an independent project, not a claim of a commercial product or an employer deployment.
