About Me

Over the last 10+ 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, including vulnerability assessments, penetration testing, and security reviews, before moving into threat intelligence and security operations. I realised early on that finding problems is only half the job; fixing them in a repeatable, operational way is where the real value lies.

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, and I enjoy building small, focused tools including GenAI assisted workflows that help teams move faster without compromising on fundamentals.

I also write and mentor alongside my work. Not for visibility, but to document what actually works, highlight common mistakes, and share lessons that teams usually learn the hard way.

My Philosophy
  • Clarity over noise: The goal isn’t more alerts it's fewer surprises. I aim for detections and processes that are simple to understand and easy to operate.
  • Automate the repeatable: If a task happens more than a few times, it deserves automation. Human time should go to judgment, investigation, and learning.
  • Trust, but verify: OSINT and telemetry are inputs not truth. I validate signals, corroborate sources, and document assumptions before escalating.
  • Build with empathy: Security should enable teams, not block them. I try to meet people where they are and make secure paths the easiest paths.
