Architecture
Modular foundations — structured, versioned tokens to page templates — built to scale across every product context and brand.
Accessibility
Inclusivity embedded into every component by default — WCAG audits, accessible patterns, inclusive design baked in from the start.
Adoption
Tutorials, onboarding, and governance — office hours and an ambassador network that make a system stick with squads, not just exist in Figma.
AI
Well-structured tokens and components give AI the context to turn generated screens into consistent, on-brand interfaces reliably.
ENGIE
2026
Leading Fluid, ENGIE's design system, across B2C, internal B2E tools, and industrial data platforms — auditing usage and gaps across teams, architecting the tokens, components, and governance that let squads adopt the system on their own.

About
From screens to systems
I started as a product designer, solving one screen at a time — until I noticed the same problems repeating, and started designing the thing that prevents them.
Now
What I'm looking for
A Lead / Head of Design Systems role — or a Senior / Head of Product Design role where systems thinking is built into how the team works.
Let’s talk!
Have a project, initiative, or collaboration in mind?
Let's connect and discuss how we can work together.
