Cybersecurity Engineer at Sunjet Corp building Python automation that streamlines healthcare security testing.

At Sunjet Corp, I assess healthcare clients’ web applications, networks, and cloud systems, then provide findings and remediation guidance. I also develop Python automation that brings Nessus and ZAP scan outputs into unified dashboards to streamline security testing workflows.

At The ODP Corporation, I managed vulnerability management across a hybrid Azure environment and used Microsoft Defender XDR and KQL for threat hunting. Earlier, at Intraprise Health, I built vulnerability management practices and security roadmaps aligned with HITRUST and HIPAA.
