Outcome

25+ screens · 2-sided marketplace

Skip the phone calls and spreadsheets — find, list, and rent heavy equipment from one app.

The Problem

Heavy equipment search was stuck in the past.

Businesses waste time and money searching for heavy equipment. Rental requests are handled manually — calls, emails, spreadsheets.

The Solution

One app. Both sides of the deal.

A cross-platform marketplace connecting equipment seekers with owners. Both sides, one app.

Key Features

Dual user mode (renter + owner) in one app

Full rental flow: browse, request, manage, and track — end to end

Equipment listing and browsing

Rental listing and browsing

Manage listings, requests, and rentals in one place

Why I Built It This Way

One app, two user types

Two separate apps would fragment the marketplace. A single app with role-switching keeps equipment supply and rental demand in the same network.

Supabase over custom backend

Solo build on a tight timeline. Supabase gave real-time sync, auth, and file storage out of the box — letting me focus entirely on the Flutter UI.
