GarageWalle

Project Overview

GarageWalle is an all-in-one automotive diagnostics, mechanics bay allocation, and auto-parts inventory tracking platform built for modern vehicle service centers.

The Problem & Motivation

Independent auto workshops relied on manual paper logs, causing misplaced parts inventory, delayed service check-ins, and poor customer visibility.
