Building security that
actually works.

Over the last 13+ years, I've worked across consulting and enterprise environments, including engagements with both government and private organisations. I began my career doing hands-on security assessments — vulnerability assessments, penetration testing, and security reviews — before moving into threat intelligence and security operations.

My core strength is taking messy, unclear security problems and turning them into practical outcomes: cleaner detections, faster response, and less unnecessary noise for security teams. I spend a lot of time working with OSINT and security automation, building focused tools including GenAI-assisted workflows that help teams move faster without compromising fundamentals.

> Philosophy

Clarity over noise — The goal isn't more alerts; it's fewer surprises. Simple to understand, easy to operate.

Automate the repeatable — If a task happens more than a few times, it deserves automation. Human time goes to judgment.

Trust, but verify — OSINT and telemetry are inputs, not truth. Validate signals, corroborate sources, document assumptions.

Build with empathy — Security should enable teams, not block them. Make secure paths the easiest paths.
