About

Staff engineer and technical product leader building the systems that other engineers build on.

I'm based in London, currently a Technical Product Manager for Terminal SDLC & Tooling at Bloomberg, where I'm focused on reimagining how engineers build and ship software in the age of AI. Before that I spent 3+ years as a senior engineer on Bloomberg's Application Frameworks team, building C++ and TypeScript runtime infrastructure.
