A pipeline that turns supplier data into ready marketplace listings for an online store.
n8n
Python
PostgreSQL
Docker
Key result
About 200 products published and updated through the pipeline.
The problem
Supplier data wasn't storefront-ready: titles, descriptions, prices and duplicates needed manual work for every product.
What I built
n8n validates incoming items, a local LLM rewrites titles and descriptions to the store's rules, prices follow a fixed formula, and publishing goes through the marketplace API with duplicate checks.
