WordPress performance help (not just plugins)

Hey,

Looking for someone who actually understands how WordPress performance works under the hood.

Not interested in “install a plugin and get 90+ score” type of stuff. More interested in how you approach caching, dynamic content, and how different layers interact.

There’s a staging setup available, so we can look at things in practice.

Before moving forward, would be good to understand how you usually think about:

caching with logged-in users
cache invalidation
CDN / media delivery

Just a quick outline of how you approach this in real projects is enough.
