Led the evolution of Fluid, ENGIE's design system deployed across ~200 active projects and ~100 teams — covering B2C consumer products, internal B2B tools, and industrial data platforms. Authored and maintained 5 interdependent Figma libraries: Components, Tokens & Foundations, Data Visualization, Sections, and Templates. * Architected a multi-theme, multi-brand token system compatible across platforms — built for scalability from day one * Structured full governance: contribution model, semantic versioning (major/minor/patch), deprecation policy, changelogs, and migration guides * Drove a 4-phase adoption strategy (Foundations → Core Components → Patterns & Docs → Scale & Adopt) with a pilot squad, ambassador network, and monthly office hours * Re-architected key navigation patterns (header, footer, sidebar) for modularity and product flexibility * Integrated AI-related components into Fluid, setting new group standards on an emerging topic * Used AI to accelerate documentation and guidelines — with the conviction that the DS is the framework that structures and qualifies what AI generates * Embedded WCAG 2.1 AA/AAA accessibility from the design stage, with per-component checklists and automated test coverage
