Building design systems that scale across brands and platforms for millions of users worldwide.

One system, many brands: I lead design systems that serve B2B and B2C products at global scale, using flexible theming, clear governance and close collaboration with engineering so teams can ship faster, stay consistent and still give every brand its own voice.

Portfolio

A selection of design systems I’ve built and led, from global consumer brands to identity verification and public services.

Expertise

Strategy & Leadership

I set the direction for the system: the vision, the roadmap and how it ties back to business goals. I work with stakeholders across design, engineering and product so the system gets the support and investment it needs to grow.

Library Design & Buildout

I design and build foundations, components and patterns, in Figma or/and in code (using AI) to move from design to working components faster. Every piece is built to WCAG standards, themeable across brands, and production-ready.

Design Ops

I set up the processes that keep a system healthy: governance, change management, contribution and request flows, and adoption tracking. The system changes in a predictable way, and teams don’t have to slow down for it.

Education & Support

I help teams use the system well, with documentation written for both people and AI, onboarding, and regular office hours. Questions get answered quickly, so teams can build with confidence.

Visual & Branding

I shape the product’s visual language, from component styling to iconography and empty-state illustrations. Together, these details create a look and feel that is consistent and clearly on-brand.

Artificial Intelligence

Design systems now have a third user besides designers and developers: AI. I make systems AI-ready with structured tokens, machine-readable docs and clear rules, so AI-generated UI stays on-brand.

About Me

I’m an UI/UX designer specialized entirely in Design Systems and Design Ops. At PepsiCo, I lead Peacock, the global Design System powering brands like: Pepsi, 7up, Lipton, Quakers and Lays.

I have worked on a wide range of different design systems: from large organisations such as the European Patent Office, to mid sized ones such as Veriff or smaller companies like CTRL.

I’m truly passionate about building scalable, accessible design solutions that empower teams and elevate product quality. With deep expertise in Figma, strategic planning and process standardization, I help large organizations deliver consistent user experiences faster.

On top of my Design System work itself, I also teach Figma and Design Systems at a local university. Furthermore, I like public speaking in relevant industry events.

The Right Amount of Salt, The Right Amount of AI @ Friends of Figma Barcelona

The Right Amount of Salt, The Right Amount of AI.

Friends of Figma Barcelona

When we cook a dish, we need to make sure we add just the right amount of salt. The same applies to AI in our Design System workflows.

In this presentation, we showed how we connected our Design System with generative AI tools. But we didn’t stop there. We also shared an overview of the different AI POCs we explored to understand how AI can support and improve our Design System workflows.

The UX Enterprise Conference

At the UX Enterprise Conference in Amersfoort 🇳🇱, I had the opportunity to showcase PepsiCo’s global Design System called Peacock.

Specifically we zoomed in on how we cover both B2B and B2C solutions in one system using flexible theming and how we overcome the challenges of scaling a Design System to a worldwide audience.

At Damn! I’m an OPS Designer, I presented “🚨 Oh no, the Design System Police is here!”, a talk on how we handle Design System compliance at PepsiCo. I shared the processes and tools we’ve put in place to maintain consistency across teams in a large organization like PepsiCo.

And believe it or not, the Design System Police left without issuing a single ticket!

Reviews

“Daan is amazing at what he does and is a wonder to work with. His work on the design system at Veriff made the whole design team’s functioning so much smoother and efficient. It was definitely the most functional and complete design system that I’ve worked with. Everything was maintained and updated with precision and great UX. Not only that, but he always worked towards the future vision of the design system, ensuring that we were constantly progressing and improving. He will be an asset to any design team looking for a key player and a delightful teammate.”

“Daan was a key piece of our design team and I was very grateful to have the opportunity to collaborate with him regularly. Daan’s impact was like a breath of fresh air, making things so much smoother for all of us.

Daan’s stood out for his thoughtfulness and his knack for spotting the little details, all while keeping an eye on the big picture and the long-term strategy of our Design System. But what makes him even more awesome is that he jumped into various initiatives and made sure designers and engineers were on the same page, upgrading processes and workflows in broader areas.

Any team that has the chance to work with Daan is in for a real treat. I am confident that their work will experience a major boost. I can’t recommend Daan enough as a fantastic team player who knows how to make things shine.”
