Security Engineer at NYU Langone Health automating clinical network security and cutting outage response time by 45%.

United States

Message

At NYU Langone Health, I built a 20+ tool automation suite to check connectivity, compliance, and network configuration across imaging devices and servers. It cut outage response time by 45% and sends posture results to Splunk dashboards.

I also designed Splunk detections for clinical network traffic and drove patch management that reduced open vulnerabilities by 38% in three months. For 60+ imaging devices, I worked with GE, Philips, and Siemens on VLAN-segmented onboarding and verification tooling.

At Bloomberg L.P., I led a Zero Trust rollout for third-party access using Okta and Palo Alto Prisma Access. I also embedded security checks into Jenkins and GitHub Actions, and built Python services that cut temporary access provisioning resolution time by 60%.

At Nicotra Group, I engineered Zero Trust access across multi-tenant commercial buildings and automated network configuration with Ansible, Terraform, and Python. I hold a B.S. in Computer Engineering and certifications including CompTIA Security+, CompTIA CySA+, and Cisco CCNA.
