I will build shopify fullstack ecosystem

Your products don't live in Shopify. They live in an ERP, a supplier feed, or your own database. I connect them.

I build headless Shopify storefronts on Next.js: Shopify runs cart, checkout and payments, while your real inventory, pricing and business rules stay in your systems.

Not a theme reskin. Recently shipped:

Diamond retailer supplier SFTP feed to PostgreSQL to Typesense search, 500k+ stones, rule-based pricing, Shopify checkout, order saga on Temporal with compensating rollback.

Fashion retailer Shopify app orchestrating every order into KeyCRM, eSputnik and Telegram, unwinding cleanly when a step fails.

What you get:

Next.js storefront SSR/ISR, SEO, Core Web Vitals, multi-language

Shopify Storefront and Admin API: cart, checkout, customers, webhooks

Sync service for your ERP, PIM, CRM, 1C or supplier feed

Search and filtering on Typesense or Algolia

Idempotent jobs, retries and alerting it survives a broken feed at 3am

Tests, CI/CD, monitoring, docs, handover. Code is yours.

Stack: Next.js, TypeScript, Go, PostgreSQL, Redis, Temporal, Typesense.

Tell me what system Shopify must talk to. Free architecture sketch and fixed scope in return.
