Custom Auto Parts E-Commerce Build

AI and inmediate offers after published are not being considered.I’m ready to move my auto-parts shop online and need a streamlined custom solution that I can maintain myself. The catalogue is small—fewer than 100 items—so performance and an intuitive admin dashboard are more important to me than marketplace-scale bells and whistles.

Infrastructure & stack
I’m already hosting other projects on Vercel, so I want the storefront deployed there. For data I currently lean toward a Heroku-hosted Postgres instance, but I’m open to smarter suggestions (Supabase, PlanetScale, etc.) if they fit better and keep the workflow simple. I own the domain; we’ll just need to point DNS correctly once the site is live. Also I need the store to be available for google, bing, searchs and the products to have tags in order to make it easy to be found.

Core requirements
• Clean, responsive storefront built with a modern framework (React or similar) and deployed to Vercel
• Admin panel where I can quickly create, edit or retire products, upload photos, set prices and stock, and toggle visibility
• Integration with my existing credit/debit card processor via a secure gateway (e.g. Stripe Elements or a comparable PCI-compliant solution)
• Shipping calculator that applies rates automatically by Argentine province (I’ll supply the rule table)
• SEO-friendly product pages and schema markup
• Environment variables and README so I can redeploy or extend without hand-holding

Acceptance criteria
1. I can add a new item and see it live—no code required.
2. A test checkout with a real card on the sandbox account succeeds and records the order in the database.
3. Entering a sample address for any province returns the correct shipping cost before payment.
4. CI/CD to Vercel passes on every push; database migrations run automatically.
5. Final hand-off includes repository access, infrastructure diagrams, and a brief video walkthrough of the admin panelT
