KadaiBid
Making card auctions simple again.
Card collectors in Brunei were running auctions through busy chat threads. Kadai Bid gave every auction one clear place. As it grew, the requirements piled up, so I went back to the core journey and rebuilt it around four inputs: photo, card, price and end time. V2 is now built, with a bid engine that stays fair when two people bid at once and an auction page that always shows where you stand.
