─ 01 · Challenge
The challenge.
Wine importers compare supplier offers by hand: emails in five languages, prices in different terms, and the number that actually matters — landed cost in EUR — computed in someone's head. The product had to run that workflow end-to-end without asking importers to abandon their inbox. And with no existing audience, the search surface couldn't be an afterthought — it had to ship as part of the product.
─ 02 · Work
The work.
The AI buyer sends RFQs to producers from a catalog of 2,000+ European wineries (the product's own claim), then handles the replies where they land: in the user's Gmail, connected via read-only OAuth so correspondence never leaves their inbox. Replies are translated and every offer is ranked by landed EUR. Around the app we shipped ~320 programmatic SEO pages inside a 340-URL sitemap — 100 wine pages under /source/, 70 import routes, 30 supplier pages, 92 price indices under /wine-prices/ — each with schema.org Product, AggregateOffer, and FAQPage markup. Engineering: React + Vite monorepo with 439 TypeScript files, Express API, Supabase, e2e tests, and an SBOM. Security: CSP with Trusted Types, HSTS preload, X-Frame-Options DENY, Cloudflare Turnstile. Stripe billing, Sentry, PWA.
