Case study Grupo Automix

A car dealership, rebuilt as a digital product.

Client: Grupo Automix
Type: Automotive platform
Role: Product & full-stack development
Year: 2026

01Overview

A digital platform for Grupo Automix, a premium dealership in Manaus: a cinematic public showroom built on their real inventory, and the multi-tenant system that runs behind it.

02The problem

Buying a premium car is a long conversation: browsing, comparing, negotiating, paperwork, test drives. It usually lives across chat threads and spreadsheets, while the website is just a catalogue.

02The approach

Treat the dealership as a product, not a website. Start from the people involved (customer, seller, supervisor, manager, admin) and design the journey each one has around the same customer and the same car.

03The build

What was actually built

01
A public showroom generated from the dealership's real listings: 26 vehicles across 19 brands, parsed from the source files and published as static pages.
02
Five role-based portals (customer, seller, supervisor, manager and admin) sharing one customer record, one negotiation and one conversation.
03
A multi-tenant core with NestJS, Prisma and PostgreSQL. Tenant isolation is enforced on the server, with granular roles and permissions.
04
Search built in from day one: per-vehicle Open Graph images, sitemap and structured data.
