About

I'm Joe. I build AI products and ship them.

I spent three and a half years at Booking.com, where I built their first AI Trip Planner and a neighbourhood search worth an estimated €19.7M a year. Before that, Appical and IBM.

In 2026 I launched Weeknights, a marketplace for clubs and events in Amsterdam. I built all of it, from Stripe Connect payouts to the search, and it now has 830 accounts and 273 published events.

I'm based in Amsterdam and work with teams across Europe. I'm also open to the right full-time role.

Have an AI feature on the roadmap?
