Cybersecurity Engineer · Washington DC

Defending what matters.

I investigate complex threats, strengthen enterprise defenses, and turn security signals into decisive action. My work spans federal and private-sector environments, grounded in more than a decade of hands-on cyber defense.

01 / Core expertise

Security expertise built in live environments.

My approach connects technical depth with operational judgment—from the first alert through containment, remediation, and executive reporting.

01

Incident Response

Lead high-sensitivity investigations, coordinate escalation, and own the response lifecycle through closure.

  • Triage
  • Containment
  • Root cause
  • Post-incident reporting
02

Threat Intelligence

Enrich indicators, connect attacker behavior to campaigns, and translate intelligence into proactive defenses.

  • IOC analysis
  • Threat hunting
  • OSINT
  • Campaign analysis
03

Vulnerability Management

Prioritize exposure through risk, threat context, and asset criticality—then validate remediation at scale.

  • Nessus
  • CVSS
  • Patch validation
  • Risk reduction
04

Security Engineering

Strengthen endpoint and network controls across complex enterprise and federal technology environments.

  • Palo Alto
  • Microsoft Defender
  • SentinelOne
  • Splunk

AI-Assisted Cyber Investigation and Incident Response

As threat actors increasingly use artificial intelligence to accelerate reconnaissance, social engineering, phishing, and other malicious activities, cybersecurity defenders must also use AI to strengthen their detection and response capabilities. AI can help analysts process large volumes of security data, correlate related activity, identify patterns, and investigate potential threats more efficiently.

However, AI should support—not replace—analytical judgment. I use Microsoft Security Copilot to accelerate investigations while independently validating its findings against the original security telemetry. Every determination remains evidence-based, whether an alert is ultimately classified as a true positive, false positive, or inconclusive.
