I've worked on a few different Design Systems

Design Systems are bigger than the team that works on them and they're the result of collaboration where everyone is working towards the same goal.

"A man has to be willing to plant a tree whose shade he'll never sit under"

People who work on design systems need to be selfless and focused on creating components and functionality that benefit those that will use it for design, for coding and most importantly, the end users of the applications that implement them.

Note: These systems are internal tools and as I'm under NDA, I can't share design work publicly but would be happy to discuss the workings of my teams, our processes and any other questions you may have.

Don't take my word for it, my teammates and colleagues had wonderful things to say about our time together.

David was in charge of the design system and always made sure to be as inclusive as possible with various team members to ensure the outcome always fit the requirements and expectations of the team, regardless of the time zone where they operated.

We worked closely with each other despite the distance between the US and EU...When I left, David took over as the Lead of the Central Design Team, and I can’t think of anyone more deserving than him.

Frank de Wit
Head of UXCE
He was a natural fit to Lead Signify's Professional Design System where he has overseen its transition to Figma, multi-brand support, tokenization, and strategic planning – managing the contributions of both internal and external designers.
