Security that works in the real world.

From complex investigations to practical defenses.

I'm a CISSP and GCFA certified cybersecurity professional with over seven years of experience spanning incident response, digital forensics, detection engineering, and security operations. My career has given me perspectives across security product support, managed security services, and in-house enterprise security.

I focus on what happens beyond the alert: understanding the failure, improving the control, and helping teams build repeatable, measurable security outcomes. Alongside my professional work, I build independent security tools and publish threat research.
