Smart location-based bidding & billing management platform connecting buyers and local sellers through real-time auctions.
Building a live bidding marketplace requires extreme accuracy and very low latency. If a bid arrives seconds late due to caching issues or slow network requests, the core integrity of the application falls apart instantly.
The client demanded a dual-login architecture where buyers could post requests within specific geographic zones, and sellers would instantly receive push notifications to compete on pricing in real-time.
We utilized WebSockets tied into a custom Node.js backend. This entirely bi-directional connection allows new bids to reflect onto buyers screens in milliseconds. We then heavily optimized the Flutter UI animations so prices updated seamlessly without screen jumping.
