After dipping into the free samples I’m super impressed with the quality of the content on https://www.greatfrontend.com/. The writing is easy to read, and the content tells a complete story that’s hard to find just by looking through blog posts.
Also, for the full stack, this guid is an amazing free resource: https://www.hellointerview.com/learn/system-design/in-a-hurry
Again, well formatted, good writing, and easy to digest.
