Aspiring DFIR Professional

I’m an IT infrastructure and cloud professional with more than 30 years of experience managing enterprise systems, solving complex technical problems, and responding to high-impact incidents and operational needs across infrastructure, endpoints, networks, identity, and cloud environments.

My experience spans Windows, macOS, and Linux systems; virtualization; networking; AWS and GCP cloud infrastructure; endpoint security and monitoring; alert triage; and enterprise operations. I hold CompTIA Security+ certification and Google Cybersecurity Professional certificate. This background has given me a practical understanding of how technology environments are built, secured, monitored, and, when something goes wrong, investigated and remediated.
