Shopify Migration: Multilingual Metafield Conversion

We need an experienced Shopify developer to fully migrate product & collection translations from one Master Shopify Store into 4 Country Stores.

Current Setup
- Master Store with 4 languages: German (primary), English, French, Dutch
- 84 products
~10 collections
- Multiple product metafields, including Rich Text metafields used for product content in different languages

Main Challenges This is not a standard CSV export/import job. Metafields with Rich Text are not exported via Shopify's normal translation export
→ Translation API workaround required Shopify IDs differ between stores
→ Mapping must be done via SKU or handle Translations must be preserved exactly for all 4 languages: Titles Descriptions Variant names (if applicable) Metafields (including Rich Text) Must ensure the mapping is correct for:
- Products
- Collections
- Any translation keys that appear in translatable resources

What we expect from you
- Fetch product translations including metafields from Master store
-Map resources correctly using SKU or handle
-Push translations into 4 Target Stores using Shopify Admin GraphQL Translation API
- Maintain support for all languages (DE, EN, FR, NL) - Run tests to validate content accuracy after migration -Provide a repeatable solution (script or workflow) in case we update translations later

Requirements -
Proven experience with Shopify Admin GraphQL API
- Experience handling multilingual Shopify setups
- Strong understanding of metafields & structured content in Shopify
- Clean logging, rollback strategy, and testing approach

Deliverables
- Full migration completed & verified in all stores
- Translation pipeline/script delivered
- Short documentation for running the process again
