OLH India

Delivered for India • Complete engineering overview, architectural decisions, and operational impact.

Executive Summary

Project Overview & Background

OLH India (Online Hands) is an ambitious mobile marketplace platform designed to connect individual vehicle owners, buyers, and certified automobile dealerships across India for buying and selling cars, motorcycles, and commercial transport vehicles.

Operational Challenge

Existing automotive classified apps suffered from rampant spam listings, unverified sellers, complex listing flows, and poor category filtering. OLH India required a robust mobile app with rapid listing creation, multi-image compression, and seller phone dialer integration.

Stem Technocrats Engineering Solution

Stem Technocrats engineered a cross-platform Flutter application backed by an atomic Laravel REST API. We implemented client-side image compression reducing 15MB vehicle photo uploads down to under 400KB before transmission, paired with location-based vehicle discovery and direct dialer triggers.
