bid.cars

bid.cars helps overseas buyers purchase cars from US auctions — a high-stakes, real-time product where every screen has to earn trust. I designed the brand, UX/UI and front-end from scratch, and have owned the design for 7+ years: bidding flows built for decisions under time pressure, total-cost transparency with customs and delivery, and risk flags that made buying blind feel safe. The platform grew to 600K+ monthly users and market leadership in Poland's US-auction import segment.
