Overview

Senior Product Engineer with 9+ years driving growth through experimentation, product analytics, and full-stack development. I specialise in experimentation infrastructure, monetisation systems, and AI-powered features, and I tend to own initiatives from RFC and stakeholder alignment through implementation to measured impact. I do my best work on autonomous teams where engineers own outcomes.
