Moodle Development Sessions

I have already an experience in PHP (Laravel,Codeigniter,Native) for 3+ years and I created many websites as a Backend developer.

I would like to have a guide on how to develop with Moodle LMS. Learning the interface is not an issue but instead developing and coding inside Moodle it has very limited resources on the web, Thus I would be glad if your time allows to give me sessions on understanding the basic ideas of how to start coding with Moodle.

What I need to learn/know:

Activities and resources
Blocks
Themes
Language packs
Course formats
Authentication plugins
Enrolment plugins
Repository plugins ?
Course enrolment
User roles in moodle
User's capabilities in moodle
Context
Permissions
Activity and course completion
Moodle Architecture
Web stack elements
General architecture
Class loader
Core global variables
Moodle APIs
Moodle forms
Moodle DB API
Logging and events API

Looking forward to hear from you.
