WooCommerce performance Case study

MU Safe Asset Cleanup

A safe MU-plugin layer for reducing unnecessary frontend CSS and JavaScript on archive, content and commerce surfaces without turning asset optimization into a checkout or admin stability risk.

Back to projects All case studies Public showcase

The business problem

WooCommerce pages often inherit global theme, builder and icon assets that are not needed on every route. The risk is that aggressive cleanup can break product cards, checkout behavior, account pages or admin previews.

What I delivered

Scoped MU modules for archive, content and home-page asset cleanup.
Route-aware boundaries so checkout, cart, admin and dynamic commerce states remain protected.
A reviewable private index that keeps the cleanup modules recoverable through Git history.

Technical approach

Separated asset decisions by request context instead of applying a global dequeue rule.
Kept cleanup rules small, reversible and grouped by surface area.
Published only the architecture and privacy boundary in the public showcase.

Result and evidence

The update reduces avoidable frontend payload risk while keeping exact production selectors, dependencies and route rules private.

Commercial value

The work supports faster browsing and cleaner Core Web Vitals work without sacrificing WooCommerce reliability.

Delivery notes

My role was to define the safe cleanup boundary, protect revenue-critical flows and keep the modules maintainable as the site evolves.

Focused on high-impact public pages first.
Avoided broad rules that could damage checkout behavior.
Kept source private and public documentation sanitized.

What this project shows

For an employer or client, this case study shows the ability to improve frontend performance inside a live commerce system without treating production safety as an afterthought.
