At Baxsecure Tech LLC, I administered network defenses and led incident response operations, including investigations, remediation, and incident review reports. I also assessed security controls against corporate policies.

At Innova Solutions / MUFG Bank, I conducted vulnerability testing and application penetration assessments, configured Splunk SIEM searches and alerts, and engineered disaster recovery workflows that maintained 98.9% system availability during business continuity testing.
