I tried codecrafter but it has too much of a jump without providing any guidance or anything for a person who might not have much knowledge about building complex projects.

I really love the idea of building small projects where you conquer one problem at a time.

As an idea there could be nothing better than codecrafter but i would like some additional reading material / guidance in terms of moving forward when you are stuck.

If i am doing something wrong let me know, would love to know how can i tackle these kinda problems.

Seconded. Not a book, but the first thing I thought of to recommend OP.
