Baivas Reverse Marketplace
Baivas inverts traditional e-commerce by putting the buyer in control. Instead of searching through endless catalogues, buyers post what they need with a target budget. Verified local vendors receive instant requests and submit competing bids directly through web and mobile apps.
Context & Friction
Shoppers waste hours comparing prices across disparate social media vendors, while small merchants struggle to find high-intent buyers without costly ad spend.
Architectural Response
A reverse bidding engine with live vendor offer queues, chat negotiation, product catalog requests, and Expo/React Native mobile applications.
Key Engineering Decisions & Outcomes
Engineered real-time price quotation feeds allowing merchants to counter-offer with custom delivery terms.
Unified web and mobile client codebases using shared state hooks and design tokens.
Built vendor verification badge workflows to ensure high marketplace reliability.
Implementation Stack & Data Flow
Modular backend with Node.js/Express, MongoDB transactional state, real-time socket events for bidding countdowns, and React Native/Expo frontend.
