What I'm looking for

I'm looking for opportunities to strengthen enterprise infrastructure and network security through hands-on monitoring, incident response, endpoint protection, and reliable technical support.

I've investigated and remediated live identity and network security incidents at JAK Energy Solutions and Trefoil Networks, including an unauthorized OAuth consent grant in Microsoft Entra ID and a DNS water torture attack on ISP infrastructure. I use Wazuh SIEM, forensic log analysis, vulnerability assessments, and automated firewall response to take incidents from detection through verified closure.

I've also strengthened endpoint, email, access, and network controls through PowerShell automation, SPF/DKIM/DMARC deployment, Active Directory administration, VPN and firewall management, and penetration testing. My work combines attacker-perspective security testing with clear technical reports and executive-ready incident summaries.
