I am looking for a full-stack team that can deliver both a responsive website and companion mobile app (iOS and Android) for an e-commerce marketplace that supports live auctions alongside fixed-price sales. Auction flow • Real-time bidding is essential; users must see incoming bids update instantly without refreshing. • After a lot closes, the platform should automatically notify the winner and trigger the checkout process. Direct-sale flow • Every product needs a clear “Buy It Now” button. • Listings must accept rich descriptions, multiple images, and variants. • Buyers should be able to rate sellers and leave written reviews that appear on the seller’s profile. Payments At checkout users may pay by credit/debit card, PayPal, or direct bank transfer. Please factor in secure tokenisation, PCI-compliant handling, and a sandbox environment for tests. Key deliverables 1. Cross-platform mobile app (Flutter, React Native, or similar) released to App Store & Google Play 2. Responsive web front-end (React, Vue, or similar) deployed to my cloud host 3. Scalable back-end with admin dashboard for product, auction, and user management 4. Payment gateway integrations for all three methods with automated settlement reports 5. Documentation and hand-over session so my in-house team can perform routine maintenance I’ll provide UI wireframes and domain once development kicks off, but I’m eager to see your proposed tech stack, timeline, and any similar projects you have launched.
