Are there any recommendations for books thats are less algorithms and more how to structure software, how to structure databases and data and how to build reliable apps/websites and reduce spaghetti code?
At the Architecture level see the very good book "Designing Data-Intensive Applications: The Big Ideas Behind Reliable, Scalable, and Maintainable Systems" by Martin Kleppmann.
For actual code, you do not have one book but have to glean the knowledge from a whole bunch of them.
