Cybersecurity Consultant with 3+ years hands-on experience in defensive security, cloud infrastructure protection, and offensive security testing.

I spend most of my time securing cloud environments, hunting threats, and breaking into systems to find vulnerabilities before attackers do. Whether it's hardening Azure deployments, responding to incidents on the 24/7 hotline, or running penetration tests, I focus on practical security that actually works. I've worked across government, transport, pharma, and critical infrastructure—dealing with everything from ransomware incidents to OT security assessments.
