WhizAuction — live bidding that never waits for a refresh.
A complete real-time auction platform across web, mobile, and admin — built with Next.js, NestJS, MySQL, Redis, Socket.IO, BullMQ, and React Native for live bids, automated auction ends, and full post-auction order foundations.
Live auctions demand real-time — rigid tools could not keep up.
The client needed an end-to-end auction platform from scratch: concurrent live bidding, automated lifecycle processing, and seamless web and mobile parity without heavy admin intervention.
No existing platform
Web, mobile, and admin had to be built end-to-end from the ground up.
Stale prices kill bidding
Live auctions required instant price updates without page refreshes.
Manual auction end processing
Closing auctions by hand was not scalable across concurrent listings.
Mobile parity required
iOS and Android bidders needed the same real-time experience as web users.
