Building systems that make complexity tractable

My PhD in Evolutionary Computation gave me a grounding in optimisation and search that turns out to be surprisingly useful when building AI systems that need to do more than generate plausible text. I've spent the last fifteen years moving between data science, full-stack development, and — more recently — the fast-moving world of generative AI and agentic systems. I've worked in pre-seed startups, post-acquisition businesses, and everything in between.
