About

I harden systems, validate controls, and improve detection posture—delivering compliance outcomes without sacrificing operational reality.

What I Do

I secure enterprise environments through endpoint policy enforcement, vulnerability remediation, and continuous monitoring. I’m comfortable operating across federal defense and commercial contexts.

How I Work

I write audit-ready artifacts, tune tools until signal beats noise, and prioritize controls that measurably reduce risk. My default: calm execution, clean documentation, repeatable outcomes.

What You Get

Strong cyber hygiene at scale: hardened baselines, validated configurations, defensible RMF packages, and monitoring that catches problems earlier.

RMF / COMPLIANCE

SSPs, POA&Ms, control validation, STIG documentation, continuous monitoring artifacts, ATO readiness support.

SECURITY MONITORING

SIEM detection logic, workflow refinement, triage playbooks, alert quality improvements, incident readiness.

VULNERABILITY MGMT

Scan/assess/validate findings, prioritize remediation, close configuration gaps, and track risk with stakeholders.
