Build a Auction Site Without WordPress

Design the Supabase schema — auctions (item, start price, reserve price, end time), bids (user, amount, timestamp), and watchlists

Build a bid placement function with database transaction that validates bid > current highest and updates atomically

Create the auction page with real-time bid feed via Supabase Realtime, countdown timer, and bid form

Implement anti-sniping — if a bid is placed in the last 2 minutes, automatically extend the auction

Set up Stripe payment intents — authorize the winning amount when auction ends and capture payment

Add email notifications via Resend — outbid alerts, auction ending soon, and winner confirmation

Build the seller dashboard for creating auctions, monitoring bids, and managing completed sales
