Shelf – Trading Platform for Collectors

A full-stack platform where collectors swap items directly — no money, no shipping, no middleman.

The Problem

Collectors trade on scattered forums and DMs: finding a matching swap and exchanging contact details safely is the hard part.

Approach

Built a Go + PostgreSQL backend with a Next.js/TypeScript frontend: list items as on-offer or wanted, browse and filter everyone's shelves, favorite items, and propose item-for-item swaps with a message.

Results

When both sides accept a swap, contact details unlock and the handover happens in person. Deployed and live, covering books, cards, vinyl, toys, and more.
