Marketplace build · 2026

The problem

Small sellers of used games, consoles, cards and comics pay high marketplace fees and have no storefront of their own. In my words

What I did

  • Built a low-fee marketplace with free seller storefronts. Verified ↗ source (opens in new tab)
  • Stripe Connect payouts, Shippo labels, eBay API, passkey login and Electron desktop apps. In my words
  • xAI vision for item identification and price research. In my words
  • Moved it to AWS behind Cloudflare on Jul 27, 2026. In my words
  • I sell on it too: "Americans Warehouse is my shop." Verified ↗ source (opens in new tab)
