Learning Pathway: Advanced Developer

Note: This learning pathway outline is still a work in progress!

This level tackles topics specific to web development but not specific to WordPress. These are skills that would apply to any software development project that makes use of the tech stack that powers WordPress (PHP/MySQL/HTML/CSS/JavaScript). There is also no specific order in which these topics should be covered, they are all equally important.

See the full Developer pathway outlined in this document.
