Professional Summary
Working at the intersection of climate science, software, and risk, I write production code for the climate, nature and supply-chain models that FTSE100 boards use to plan their next decade, lead applied AI work in agricultural risk, and have helped design data platforms launched at COP28 by heads of state. Most of my career has been spent moving between technical, scientific, policy and commercial worlds, and it’s the kind of work I love most: deeply technical, genuinely useful, silently impactful.
