WooCommerce performance Case study
MU Safe Asset Cleanup
An MU-plugin layer that strips unnecessary frontend CSS and JavaScript from archive, content and commerce surfaces, without turning asset optimization into a checkout or admin stability risk.
The business problem
WooCommerce pages inherit global theme, builder and icon assets that most routes never need. The risk runs the other way too: cleanup that is too aggressive breaks product cards, checkout behaviour, 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
- I decide about assets per request context instead of applying one global dequeue rule.
- I keep the cleanup rules small, reversible and grouped by surface area.
- I publish only the architecture and the privacy boundary in the public showcase.
Result and evidence
The cleanup takes avoidable weight off the frontend, and the exact production selectors, dependencies and route rules stay private.
Commercial value
Shoppers get lighter pages, and Core Web Vitals work gets easier, without giving up WooCommerce reliability.
Delivery notes
I had to draw the safe cleanup boundary, protect the revenue-critical flows and keep the modules maintainable as the site changes.
- I went after the high-impact public pages first.
- I avoided broad rules that could damage checkout behaviour.
- I kept the source private and the public documentation sanitized.

}What this project shows
This one shows I can improve frontend performance inside a live commerce system without treating production safety as an afterthought.
