about me
Alexander Kaan
Amsterdam
I design interfaces and build them. Eighteen years in the trade: ten in advertising, the rest making products. Lately open-source UI tooling.

Play with your app's design. Right in the browser.
Configure your UI in your browser, or straight from your agent via MCP. Every colour, font, radius and spacing in its CSS becomes a knob, and the real app follows 1:1. Nothing is sent to a server and nothing is stored: close the tab and it is all undone. The code comes out as a patch, design tokens, or a DESIGN.md for your agent.

Photography
What started out as a way to shoot real photos for client websites, instead of using stock, branched out into street photography and portraiture. From there came event work for clients like HSBC Innovation Banking, Gemeente Amsterdam and 10 Club, and lately advertising and editorial photography for fashion and sports brands.
