I make complex things make sense.
I'm a Product Design Leader working where product, design and technology overlap. For more than 20 years, I've been turning tangled problems into systems people can understand, use and build on.
From many sources to one usable solution
Not case studies.
These are arguments. The projects are the evidence.
80+ projects. 15 years. A lot of interfaces.
Before leading Product Design, I spent more than a decade working independently as a UX/UI designer and frontend developer, long before either was a well-defined job title.
The technology changed. The underlying question stayed remarkably consistent: How can we make something complex easier to understand and easier to use?

AI is progress: now you can make the same mistakes faster.
Which is the whole case for judgment.
Good leadership is mostly about creating clarity.
People don't need every answer. They need to know what matters, why, and what they can own.
I like complex problems. I just don't like complicated solutions.
Complexity is where the interesting work is. Complication is a solution that gave up.
If only one person understands the system, it isn't a system.
It is a dependency with a nice interface.
The best solution is the one that survives contact with reality.
A concept nobody can build is not a solution, it is a slide.
Good design is not decoration.
It is a way of making decisions visible.

The World Wide Web was still young. I worked on the Safety Guide for Experiments. Somewhere along the way, I met Tim Berners-Lee. I did not yet know that the web would become my professional home for the next 30 years.

Independent UX/UI Designer and Frontend Developer. 80+ projects. UX, UI, Frontend, Data visualization, Design systems. Long before “Design Systems” became a job title, I was building pattern libraries because maintaining the same interface in twelve different places seemed like a bad idea.

What's next
I am interested in roles where product, design, technology and people need to come together. Especially when the problem is complex enough that the obvious solution is probably wrong.
