Bidstation
Project overview

What we built.

BidStation is a real-time mobile auction platform that connects buyers and sellers through seamless bidding and secure transactions. Developed for iOS and Android, the app features live and scheduled auctions, dynamic product listings, push notifications, and bid tracking. A key highlight is its integration with Square Terminal, enabling smooth in-person and online payments via credit/debit cards and digital wallets. Built with React Native (or native Swift/Kotlin), Node.js, and WebSockets/Firebase, BidStation ensures fast, reliable performance while maintaining robust security and scalability.

Designed an intuitive UI/UX, implemented real-time bidding, and integrated Square’s payment APIs to streamline transactions. The app bridges the gap between physical and digital auctions, offering sellers a dashboard for listings and analytics while giving buyers a convenient way to bid and pay. By combining Square’s trusted payment ecosystem with a user-friendly interface, BidStation enhances engagement and trust in the auction process.
