Closeby
Location-based social marketplace connecting neighbors to trade, hire, and help each other
Overview
Closeby is a hyperlocal mobile platform where users discover nearby service providers, buy and sell items, post community requests, and chat in real-time. Built as a monorepo with an Elysia (Bun) API, a React Native (Expo) client, and a SvelteKit admin panel — all tied together with end-to-end TypeScript type safety via Prisma and Eden Treaty.
