From building software to changing how organisations work.

I started in engineering, writing early code for a healthcare SaaS platform that would go on to serve more than 2.5 million patients. Over the following decade, I moved through engineering leadership, product, solutions architecture, and running a European business.

Financial services added another dimension. At Deriv, I led products, teams, and operations, then built an internal agentic AI platform from scratch. Getting 100 workflows into production meant working through the details: model selection, evaluations, access controls, audit trails, and the realities of adoption.

Today, I’m Head of AI Transformation at FP Markets. I bring a practical view of what AI can change, and an engineer’s curiosity about how to make it work reliably.

Curiosity doesn’t stay in one industry.

My independent AI safety research explores model circuits, refusal, unlearning, and the measurements we use to understand them. I publish experiments and results openly, with an interactive guide that makes the work easier to explore. Explore my AI safety research.

Outside my day role, I build PLA Health and research Bitcoin forensics through TrailBit Labs. The subject matter changes, but the questions stay connected: what does the evidence support, how do we make uncertainty visible, and what happens to the person relying on the answer?

I explore those questions in Frontier Field Notes, my newsletter on Substack and LinkedIn, and in my podcast archive. I’m interested in conversations that connect disciplines and challenge assumptions.
