WooCommerce is powerful and easy to destabilise. One careless plugin can slow checkout, break tax display, or fight the theme on the cart page. Store engineering here means the storefront is treated as the revenue path it is: changes are staged, tested against real customer flows, and shipped with a rollback ready.
Typical work: custom store builds, checkout and cart fixes, product data restructuring, payment and shipping integration, and untangling stores that have accumulated years of conflicting plugins.
