01 — About
Infrastructure with
security in mind.
I'm an Infrastructure Security Engineer working across security operations, infrastructure, networking, identity, and automation.
My work sits between traditional infrastructure and cybersecurity — keeping systems available while making them more secure, observable, and manageable.
I enjoy working close to the infrastructure: servers, networks, firewalls, SIEM, storage, virtualization, and the automation that connects everything together.
