Why you should
hire me

More than data driven and user centered. I find joy in chasing details.

Like individual brush strokes of a master painter, they don't look like much in isolation, but looking at the full picture will leave you in wonder. Your products can do the same, let me show you how.

A little bit about me

Born in South-Africa and grown up in the Netherlands, I now answered the call of love and moved to Switzerland where my UX journey continues! Every new assignment means meeting new people and embarking on a new adventure.


Other than creating beautiful apps, you can always get me up for some boardgames, surfing, long-boarding & spontaneous adventures!

Need a UX'er on your team, or someone to make your app happen? Give me a call!
