About

Bridging the gap between OT ambition and security reality

Most organisations working with operational technology understand their systems. What they often lack is a clear direction for securing them — and the bridge between that ambition and day-to-day execution. That's where I work best.

My background is in industrial automation: PLC, HMI, SCADA environments where operational continuity isn't optional. That foundation shapes how I approach cybersecurity today — not as a compliance layer, but as part of how organisations are designed to be resilient.

What energises me is the space between strategy and delivery. Setting a clear direction, translating it into concrete steps, and working with people to make it real. I combine technical credibility in OT and security with the leadership work of building structure, ownership, and momentum.
