Fix Magento 2 Stock issue

Looking for an experienced Magento 2 developer to resolve a critical issue: the store has stopped deducting stock quantities when orders are placed. The product quantity remains unchanged in both the admin panel and on the frontend product page.

The task will require in-depth debugging — tracing Magento 2’s observers, plugins, cron jobs, and database triggers to identify where the default inventory deduction process is being bypassed or overridden. Strong expertise in Magento 2 core logic, PHP, MySQL, Composer, and CLI troubleshooting is essential for this role.
