Engineering the platforms on which the future is built.
I build technology organisations that can turn a strong idea into a dependable product and a durable platform. My work brings together engineering strategy, product ambition and the operating disciplines that support quality as an organisation grows.
I am particularly interested in the choices that compound: architecture, technical leadership, developer experience and the way teams learn from production. The CTO's contribution is to make those choices understandable to colleagues who are accountable for customers, capital and commercial outcomes.
I lead through a combination of technical depth and organisational clarity. I value small, capable teams, explicit trade-offs and a culture in which engineering judgement develops alongside the systems we build.

In my own words
Engineering choices shape what a product can become. I invest in architecture, technical leadership and developer effectiveness so teams can move with confidence. Reliability and delivery speed are decisions to design together, with trade-offs made explicit.
