About
Network Security Engineer focused on practical, measurable security outcomes: reducing lateral movement, hardening ingress/egress, and building detection that operators trust. I work best where security is treated as engineering—clear threat models, predictable change control, and automation-first baselines.
Security Architecture
Trust boundaries, segmentation strategy, control selection, and audit-ready documentation.
Network Defense
Firewall policy engineering, VPN hardening, secure admin access, and safe rollouts.
Incident Response
SIEM mapping, alert tuning, triage workflows, and containment playbooks.
Automation
Policy-as-code, repeatable baselines, drift detection, and change governance.
