AutoPars
Auto parts marketplace with vehicle compatibility, PWA, 3 panels and 5 integrations

The challenge
Traditional auto parts marketplaces throw thousands of generic categories together — accessories, tools, everything — making it hard for repair shops and buyers to find the right part for the right vehicle. The result: endless searching, wrong purchases, and constant returns.
AutoPars needed a platform focused exclusively on the auto parts ecosystem, with a vehicle compatibility system that matched every part to the correct make, model, and year — something no general-purpose marketplace offered natively.
The solution
I built a full B2B2C marketplace from scratch with three access layers:
For buyers (repair shops and consumers)
- Catalog with vehicle compatibility filtering, make → model → year
- Browse by vehicle system: engine, suspension, brakes, electrical, cooling, body
- Advanced search: by SKU, name, or OEM code
- New or used part labeling on every listing
- Seller location for shipping cost calculation
- Favorites and shopping cart
For sellers (businesses and individuals)
- Product management panel with SKU, price, stock, and status
- Low stock alerts and paused item controls
- Sales history per product
- Exact vehicle compatibility registration
- Listing of new and used parts
For platform administration
- Full dashboard with total GMV, platform revenue, and percentage growth
- Seller management: active sellers, open disputes, and pending withdrawals
- Monthly GMV chart and order distribution by status
- Top sellers ranking by volume and revenue
- User, product, financial, and settings management
Integrations
- Asaas: payment processing and split between platform and seller
- Melhor Envio: automated shipping quotes and label generation
- Resend: transactional emails (order confirmation, shipping status)
- Z-API: WhatsApp notifications for sellers and buyers
- Cloudflare Stream: product video hosting and optimized images
Astro landing page
Since the marketplace is a React SPA (client-side rendering), organic indexing is limited. The Astro LP solves that: static HTML, Lighthouse 95+, and content optimized to rank. It works as the organic entry point to the marketplace and a showcase for new sellers and investors.
PWA (Progressive Web App)
Installable app on sellers’ phones for managing products, orders, and real-time notifications. Training videos delivered separately for onboarding new sellers.
Results
- Fully working marketplace with catalog, checkout, and admin panel in production
- Vehicle compatibility system that eliminates wrong purchases
- 3 distinct panels (buyer, seller, admin) in a single platform
- 5 external integrations running in real time
- Admin dashboard with full visibility into GMV, orders, and sellers
- Astro LP as an SEO layer, solving the React SPA indexing limitation
- Installable PWA for sellers with integrated training videos
- Strategic bonus deliverable the client didn’t ask for but needed
