Multi-brand complexity
One shared system had to support different brand expressions without creating separate component libraries for every brand.
Case Study
UNIFY Design System
UNIFY is REWE International's internal design system infrastructure for building consistent enterprise products across multiple brands. My work focused on shaping reusable components, semantic foundations, documentation, and system patterns that helped product teams design with shared logic instead of rebuilding the same decisions from scratch.
Overview
UNIFY is not a single brand UI kit. It is the shared ground that lets multiple brands diverge visually without diverging structurally. The system connects semantic foundations, reusable components, interaction patterns, and documentation into one shared product language.
My work focused on the infrastructure beneath product screens - the decisions that make interfaces scalable, consistent, and easier to maintain across teams. Instead of treating components as isolated UI elements, the system frames them as reusable decisions that can survive brand variation, product complexity, and long-term team changes.
Context / Challenge
A multi-brand enterprise system has to support more than visual consistency. It has to work across different product teams, release cycles, platforms, brand expressions, and implementation constraints. A change in a shared foundation can affect many surfaces, so every decision needs to be stable, reusable, and clearly documented.
The challenge was to create a system that gave teams enough structure to move faster without removing the flexibility they needed for real product work.
One shared system had to support different brand expressions without creating separate component libraries for every brand.
Multiple product teams needed a common foundation for navigation, forms, data-heavy workflows, feedback patterns, and page structures.
The system needed to be understandable not only for current designers and developers, but also for future teams inheriting the work.
My Role
As a Senior Product Designer, I worked on UNIFY alongside enterprise product work, turning recurring product needs into reusable system decisions. My contribution focused on component design, reusable patterns, semantic foundations, documentation, and cross-functional alignment with product and engineering teams.
I owned the translation layer between live product delivery and the design system itself. Real workflows, stakeholder feedback, and multi-brand constraints flowed in as inputs; reusable components, patterns, and documentation flowed out as scalable system decisions other teams could adopt without rebuilding the same logic from scratch.
Architecture
UNIFY was structured as four connected layers that turned design decisions into scalable product delivery. Foundations defined the system rules, components transformed them into reusable UI, patterns solved recurring product workflows, and resources enabled teams to adopt the system efficiently.
Foundations
In UNIFY, tokens were more than visual values. They created a shared semantic layer that allowed multiple brands to use one scalable design system without duplicating components.
I worked with token structures that separated primitive values, semantic roles, and component-level usage. This made theme changes faster while keeping interface behavior stable.
The result was stronger consistency across products, easier handoff between design and development, and faster rollout of new brands.
Component Library
UNIFY contains a broad inventory of reusable assets supporting enterprise, B2B, B2E, B2C, and internal product environments. The system extends beyond basic UI controls into navigation patterns, data-heavy workflows, page templates, and specialized modules used across multiple product contexts.
Each asset is designed for reuse, documented for adoption, and aligned with implementation expectations. This turns the library into operational infrastructure rather than a visual inventory.
Featured system elements
Selected UNIFY system elements demonstrating experience in reusable enterprise patterns, scalable navigation, structured layouts, and dense operational interfaces.
A reusable enterprise header pattern for product identity, search, user context, notifications, and shared utility actions.
Used across multiple internal tools for navigation consistency.
A scalable side-navigation pattern for enterprise tools, supporting nested sections, product areas, active states, and fast access to key workflows.
Enabled scalable navigation for multi-module enterprise products.
A page-level pattern that gives users clear orientation, hierarchy, supporting context, and access to primary actions across complex enterprise products.
Improved orientation and action discoverability in complex workflows.
A complex data-display component for enterprise workflows, supporting dense information, filtering, sorting, selection, inline actions, states, and pagination.
Critical for dense operational data and productivity flows.
REAL PRODUCT IMPACT
As Product Designer, I led the transformation of a legacy internal product into a modern enterprise platform. Working closely with the Product Owner, Business Analyst, developers, and key stakeholders, I helped redesign workflows, improve usability, and build a scalable product foundation using a shared design system.
The result was a faster, clearer, and significantly more efficient application that delivered measurable improvements across key operational metrics.
An outdated internal web product was completely reimagined into a modern, high-efficiency platform. Through improved UX architecture, clearer workflows, reusable components, and stronger collaboration across teams, the new solution significantly outperformed the legacy version.
The mobile product experience was rebuilt using the same scalable foundations, improving clarity, consistency, and speed across everyday user tasks.
While confidential internal figures cannot be publicly disclosed, post-launch performance showed substantial improvements across productivity, usability, and delivery speed. The redesigned platform also received highly positive feedback from internal users and stakeholders.
SYSTEM EVOLUTION
Live product delivery revealed which components needed refinement, where patterns were missing, and what teams needed to move faster.
Working closely with Product Owners, Business Analysts, developers, stakeholders, and users helped translate business complexity into scalable system improvements.
User tests, implementation feedback, and real workflows continuously informed better components, stronger patterns, and smarter foundations.

Better future products
As Product Designer, I worked on enterprise products built from scratch and large-scale migrations from legacy systems. Real delivery exposed component gaps, missing patterns, workflow friction, and new business needs — which became opportunities to strengthen the design system itself.
The most valuable design systems are not built in isolation. They improve through real products, real constraints, and real collaboration. My contribution was helping turn delivery learnings into scalable system progress.
