Mobile Marketplace for UK Tradespeople

A mobile marketplace for UK tradespeople to buy and sell surplus building materials — built by someone who’s actually done the refits.

The Problem

Every building job produces leftover materials. There’s no marketplace designed for how builders actually think about surplus stock. Facebook is too generic. eBay charges too much.

Built by a Tradesman

I’ve done national pub refits, run a motorcycle workshop, and managed multi-site building projects. The categories, listing flows, and search logic are designed around how tradespeople actually think.

The Build

React Native with Expo for cross-platform mobile. Supabase handles real-time backend — listings, user profiles, messaging, and transactions through PostgreSQL with real-time subscriptions.

The Result

A purpose-built mobile marketplace that speaks the language of the UK building trade. The best software comes from understanding the domain first.
