Bridgo 2.0
A full-stack bidding ecosystem connecting local street vendors with raw material suppliers through location-aware live auctions and event-driven communication.
The Objective
Bridgo 2.0 digitizes the unorganized procurement chain of local vendors. By replacing manual, opaque pricing with a transparent Live Bidding system, it empowers small businesses to source materials at competitive, real-time rates.
"Transforming local supply chains from static manual orders to dynamic, location-aware bidding wars."
Bidding & Notification Pipeline
Geo-Aware Registration
Hierarchical location system (State → City → Area) using Browser GPS to map users to their local commercial hub.
Live Auction Rooms
Suppliers broadcast material requirements; vendors join specific Socket.IO rooms to place dynamic bids.
Real-time Event Stack
Unread counters and unmount-safe notifications keep users updated on bid status and auction victories.
Dashboard Synchronization
Role-based interfaces update DOM elements instantly as bids are accepted or outbid.
The Bidding Logic
socket.to(auctionId).emit('newBid')
Utilizing Socket.IO Room Management, the system ensures that bid updates are only transmitted to active participants of a specific auction, minimizing server overhead.
📍 Location-Aware Architecture
Stores precise coordinates for future implementation of delivery radius filtering and nearest-neighbor supplier matching.
🔔 Role-Specific Notifications
Dual-channel notification system: User Rooms for personal alerts and Auction Rooms for competitive bidding activity.
System Tech Stack
Platform Interface
Experience the real-time bidding environment and dual-role dashboards.
Challenges & Refactoring
Asynchronous Synchronization
Maintaining a consistent auction clock across hundreds of clients using server-side timers and event broadcasting.
Hierarchical UI Rendering
Building a dynamic location picker that pulls dependent data (Cities → Areas) without refreshing the registration flow.
