EDENbazar
An automotive marketplace for a Slovak dealership selling warranty-backed vehicles from operational leasing. Three-language platform with automated social media publishing and real-time sync across 6 external platforms — replacing manual listings with a unified marketplace.
Project Overview
EDENcars operates a unique business model — buying new cars, leasing them for approximately one year through operational leasing, then selling them with remaining factory warranty. Managing their inventory across their website, Facebook, Instagram, Google My Business, Autobazar.eu, and other platforms required separate listings, pricing updates, and photo uploads on every channel.
We built a unified marketplace platform with a GraphQL API serving 70+ fields per vehicle, an authenticated admin panel for inventory management, and automated cron jobs handling social media publishing and Google My Business sync. The platform supports 3 languages across 42 route variants, generates XML and RSS feeds for third-party marketplaces, and processes images with branding overlays and authenticity badges — all managed from a single admin interface.
