Cardino
B2B marketplace for electric-vehicle stock
Cardino.de is a Berlin marketplace where businesses trade electric-vehicle stock, with DAT vehicle data behind the listing.
Cardino marketplace screens and the public cardino.de site.
What we did
A professional EV buyer does not trust a photo and a price. Cardino is the B2B marketplace for that stock. Bubble is the commercial front end. Supabase holds accounts and listing data. DAT supplies the vehicle identity and specs a German buyer expects. OpenAI is used only where a repetitive text task is faster than typing, not as a layer over missing vehicle data. I tied those parts into a desk a dealer can run during the day. The screens mix the public site and the working marketplace.
