I build design systems with rules your team can use.

I start with the patterns your product already needs.

Complex software repeats decisions across screens: selecting records, filtering a table, showing a status or handling a form error. I review those patterns in your product and look at where the design files and implementation disagree.

That review helps define the scope. Your team might need a component library, clearer usage guidance or a focused review of an existing system.

I document behavior alongside appearance.

I define the component states and usage rules that affect implementation. A table needs a clear selection model. A form needs error and disabled states. The documentation should explain how those decisions work across the product.

I work with your engineers to connect the design guidance to what they can build and maintain. I agree the component scope and documentation with your team before starting.

I have worked with both new and established systems.

At IMO Health, I worked on a company-wide design system for clinical products. At United Airlines, I reviewed a vendor interface against the Orion design system and translated findings into specific interface requirements.

The Safety Hub case study shows how that review related to usability research and the vendor's implementation work.

If the immediate concern is a workflow people struggle with, a focused UX audit can help define the changes before extending the library.

I define a scope your team can maintain.

I start by reviewing the current design files and the implemented product with your team. I need to know who uses the library, which patterns are repeated and how your engineers maintain their components.

A focused engagement can cover an audit of the library, a set of component designs or usage documentation. I agree those outputs with you before starting, including who will own future changes.

I work from Utrecht with teams across Europe and North America. I keep reviews connected to the product work, so the library is assessed against the screens your team needs to deliver.
