Security-minded. Systems-grounded.

I am an IT and cybersecurity professional interested in the places where infrastructure, monitoring, and incident response meet.

My work spans Active Directory, network and system security, SIEM operations, PowerShell automation, and hands-on defensive labs.

FOCUS       security operations · systems administration · hardware infrastructure
BUILDING    challenging labs, practical tools, and clear technical documentation
STUDYING    CompTIA Network+ (N10-009)

My Workflow

observe  → establish what normal looks like
verify   → test assumptions against evidence
contain  → reduce exposure without losing service uptime
improve  → automate, document, and make the next response faster
