Working demo

Four demos from daily practice

No screenshots but working screens. Each demo shows how I turn a real question into something you can use straight away: a dashboard that recalculates, a pipeline you drag, a segment that counts along live and a calendar you reshuffle.

Four screens I thought up, designed and built myself, from the design down to the JSON API underneath. They run on invented data, but the questions behind them come from the work I did at KBenP, Ahold Delhaize, HyperMe Marketing and Unicorn Displays.

Why demos and not a list of bullet points

A CV tells you what someone has done, a demo shows you how they think. Every demo starts from a question I was actually asked, shows the choice I made and the number that comes out of it. At the bottom of each demo you can see which project from my CV it goes back to.

What you are looking at

Click through the demos and use the filters. Everything recalculates live, none of it is a screenshot. They work with the keyboard too: the deal cards and the posts in the calendar move with the arrow keys.

The demos pull their numbers from a JSON API on this site, so filters and calculations really run instead of being baked in.

Every number on this page is invented sample data, built to look realistic on purpose and calculated live by a JSON API on this site. No client data is used and no existing organisation is imitated. I would rather show what I can do than write it down.
