Rhys has led teams and departments through architecture, security and governance work (including a unified knowledge graph and GitHub enterprise SSO migration) and is a maintainer of the popular fetch-mock testing library. He favors maintainability and test-driven development over chasing trends, and has a track record delivering measurable performance and reliability gains (helping make FT.com one of the fastest news sites). Comfortable spanning product, people and code, he also brings an analytical background (first-class maths degree) and an uncommon mix of design-system, CDN/serverless and data-governance experience.
