Java developer with Shopify and ETL experience

Need a Java developer to update code used to upload products to Shopify.

The current code transforms supplier provided CSV data sheets to the Shopify Product Upload CSV format. I need someone who can use my code to upload new supplier data formats. This will ensure that the look and feel of the product pages are standardized, it follows the rules for classifying and tagging the products, and optimizes for SEO. So essentially the existing code is an ETL tool built for my Shopify store in Java.

I currently have 5-6 supplier sheets ranging from 10 products to hundreds of products. Data cleaning and preparation of the supplier data will be required to make sure it can be fed into this ETL Upgrade to see actual info's also a position that will keep growing since I am always getting data updates and new supplier data sheets.

Skills:
Java
ETL
HTML
CSS
Shopify (preferred, but not required)

Assistance will be provided so you can get up to speed on the code. Please provide contact information.
