Challenge

Create a Design System capable of supporting a growing number of brands
Automate UX/UI flow conversion across devices and brands using design tokens
Ensure accessibility and ease of use for all teams, from UX research to UI design
Enable flexible brand customization without overloading the core system
Build a centralized Design System team to support local teams while respecting brand-specific needs

My role

As Design System Administrator and Process Optimization Strategist, I was responsible for designing and building the overall DS structure to promote speed, cohesion, and team autonomy. My focus was on creating a scalable foundation that could serve both immediate operational needs and long-term product evolution across multiple brands.

I developed shared standards capable of supporting each brand's specific requirements, while maintaining a unified design language. Throughout the project, I continuously monitored, audited, and iteratively improved the system to ensure it remained robust, flexible, and aligned with the team's evolving workflows.

What was my contribution?

Preliminary Analysis of the Operational Context

As-Is Mapping Across All Brands:
We began by mapping the current UX/UI structure of each brand involved, identifying key differences in workflows, visual standards, and process flows.

Primary Flow Analysis (Sisal Reference):
Sisal was selected as the "core brand" to define the foundational flows, ensuring coherence and scalability for the future onboarding of additional brands.

Structuring the New Multi-Brand Architecture

Decision-Making Process and Team Analysis:
Through interviews with local teams, we analyzed their operational workflows, pain points, and priorities to shape a flexible yet coherent system.

Multi-Brand and Multi-Language Token System:
We developed an advanced tokenization schema enabling automatic adaptation of components, themes, and flows according to brand identity and language.

Automation of Flow Conversion:
New mechanisms were implemented to allow teams to create user flows through drag-and-drop assembly of components, eliminating the need to rebuild flows from scratch.

Practical Implementation and Rollout

Component and Asset Construction:
Each component was designed for maximum reusability and easy customization, while maintaining high-quality standards across brands and devices.

Automation Testing and Pattern Validation:
We extensively tested the DS automation engine across brands and devices to validate system robustness and ensure efficient flow conversions.

Zeroheight Documentation and Onboarding:
All flows and components were documented with practical guides, usage examples, video tutorials, and quick references to accelerate adoption across teams.

Initial Usage Monitoring and Feedback Loop:
Rapid feedback cycles were activated with design teams during the first deployments, allowing us to correct issues and optimize the system iteratively before the full rollout.

Results and impact

FLOW CONVERSION SPEED

-100% reduction in flow conversion time compared to manual processes

SUPPORT REQUESTS REDUCTION

-70% decrease in support intervention requests from operational teams

IMPLEMENTATION ERROR ELIMINATION

-100% reduction in errors during component selection and implementation

BRAND INTEGRATION EFFICIENCY

+4 brands successfully integrated within approximately 6 months, without any delivery delays

Final thoughts

In complex projects like this one, building the system is only half the challenge — the other half is helping teams evolve the way they work. This experience represented a collective growth journey, bringing together different operational cultures under a shared framework. Cross-functional collaboration and a strong willingness to improve turned what began as a technical challenge into one of the most rewarding experiences of my career.
