E-commerce Data Scraper Repair & Upgrade

We have an existing, working automation module that was previously scraping product data from major Indian e-commerce websites and uploading listings to eBay.com and Wix Stores.

Due to recent structural changes on source websites and/or API updates, the system has partially or fully stopped working. We are now seeking a senior developer or experienced automation agency to audit, repair, upgrade, and harden the current system for long-term reliability.

This is not a new build. The objective is to fix and stabilize what already exists, with improvements only where genuinely required.
