Julien Baudic

I'm Julien, a UX & Design System Designer at MMA.
I design and scale systems that connect people, products, and ideas.

I'm a design leader focused on aligning product design, UX strategy, and system thinking across complex, multi-product environments. At MMA, I lead UX and design system initiatives, building the frameworks and governance models that help teams scale design quality, strengthen strategic alignment, and collaborate effectively across the organization.

I also serve as the product lead for my team, driving vision, roadmap, and execution. I also establish and implement UX standards for AI-enabled products, maintaining coherence, clarity, and confidence as AI becomes central to the platform.

With my team, I lead the Design System MCP, embedding AI directly into the design system to accelerate exploration and solutioning. By putting UX patterns and system knowledge into the hands of designers, PMs, and engineers, we enable everyone to become a maker.

Effective systems stay in the background, empowering teams through structure, consistency, and shared understanding.

To showcase and structure this work, I created a dedicated initiative called Quadrilogy. This project presents the strategy, methodology, governance model, and impact of the Design System at MMA.

My work bridges system strategy and governance, product management, design operations and AI automation, cross-functional collaboration, UX scalability, accessibility, and design mentorship, establishing the foundations for consistent, high-quality experiences at scale.
