Sample Wordpress custom page on custom post type with ACF

I m a newbie with wordpress and I need a sample in how to develop a simple custom page that save ACF data to standard wordpress database, with standard field and images repeater. Including 1 hour online of Q&A on sample of code.

I have one main Job Post Type with some custom attribute and I need a page to mantain these fields . For each Job type I can submit different images ( which is another custom post type ) and several resources (which is another custom post type ). The page should give the possibility to CRUD the Job and add images and resources.
