About.
I designed a complete Design System from scratch for two major products that previously lacked visual consistency.
- Existing interfaces audit to identify recurring needs in components and design patterns.
- Creation of adaptable UI components for both white and dark modes (design tokens, Figma libraries), tailored to the specific needs of each product while ensuring consistency, accessibility, and scalability.
- Set up clear and structured documentation to ensure smooth adoption by both tech and design teams (naming conventions, best practices, usage variations, responsive behavior, etc.).
- Closely collaboration with developers to ensure accurate implementation and strong alignment between design and code, with regular syncs and follow-ups. Used Storybook as a shared tool for development.
- Set up workshops and regular design rituals with product teams to continuously improve the system based on real feedback and evolving business needs. Management of versioning and system updates.

Challenge.
Ensuring consistency while maintaining flexibility
Balancing the need for visual and functional consistency across product.Thinking at scale from the start
Designing an evolving system that can easily adapt to new use cases, products, themes (dark/light mode), and contexts (responsive, accessibility, internationalization, etc.).Effective collaboration with tech teams
Ensuring perfect alignment between design and development: choosing common tools (Storybook), integrating technical constraints, sharing naming conventions, and validating coded components.Managing adoption and change
Training and supporting teams to ensure smooth adoption of the Design System. This includes clear documentation, educating on best practices, and listening to internal user feedback.Maintaining, iterating, and governing over time
Establishing rituals to maintain system quality, evolve it based on feedback, prioritize updates, and manage incoming requests without compromising structure or efficiency.
Result.
Consistency
& Coverage
100% of product interfaces covered by Design System components within 10 months
Development Velocity
Reduction in UI development time per feature
→ Tech team: time saved by reusing coded components via Storybook.
Adoption Rate
Developers, product team onboarded, new features built using the system
→ PM / Design team: system usage rate across teams and products.

"Thanks to Murielle, the Design System was not only implemented smoothly, but she also found and established effective collaborative solutions and processes. She successfully led the project, ensuring that the product is easy to adopt and use for any new team member."
