Scalable Design System & Experience Hub

Senior UX Designer | Design Systems & UX Leadership

Co-led the design and scaling of a responsive design system and experience hub for a medical enterprise client, enabling consistent multi-platform delivery while growing and mentoring a cross-functional design team.

Led the design and scaling of a responsive design system and experience hub for a medical enterprise client, enabling consistent multi-platform delivery while growing and mentoring a cross-functional design team.

The challenge was twofold:
• Create a responsive, scalable design system adaptable to multiple platforms
• Enable internal teams to adopt and evolve the system sustainably

My role & Approach

I worked as a Senior Product Designer and Design Systems Lead,
acting as a consultant embedded within the client’s organization.

My responsibilities included:
• Leading the definition and evolution of a responsive design system
• Ensuring consistency across web and mobile platforms
• Aligning system governance with the client’s internal workflows
• Leading and mentoring a growing team of UX and UI designers

From Complexity → Structure

The design system was built to support both web and mobile products, ensuring consistency while respecting platform-specific patterns.

 

Components were designed to:


• Adapt responsively across screen sizes
• Support accessibility and medical compliance requirements
• Scale as new products and features were introduced

Experience Hub & Adoption

To support adoption and long-term scalability, an Experience Hub was created as a single source of truth for designers, developers, and product teams.

The hub documented:
• Component usage guidelines
• Interaction patterns
• Design principles and best practices

Team Leadership & Growth

Beyond system creation, a key focus was on growing and strengthening the design team

I co-led and mentored a team that grew from 4 to 6 designer spanning both UX and UI specializations.

My leadership focused on:
• Clarifying roles and responsibilities
• Supporting skill development across disciplines
• Establishing collaboration standards with development teams
• Creating space for designers to contribute strategically, not only visually

Impact & Outcomes

• Enabled consistent, responsive experiences across web and mobile platforms
• Reduced design inconsistencies through shared components and guidelines
• Improved cross-team alignment between design and development
• Increased team capacity by scaling from 4 to 6 designers
• Established a sustainable foundation for future product growth
