"Ang mga hooks na bumago sa buhay ko": D8 key hooks and customizations that helped me grow as a backend dev

1. hook_node_access_records/grants
2. Overriding contrib service classes
3. Overriding entity classes


After 2 years of working (mostly) exclusively with D8, I will show how we used these in order to solve some of our client's requirements and hopefully you can apply these to your own projects as well.
