Recommended books for a self taught software developer

I'm a self taught developer (of 4 years) and have been working professionally as a developer (working mostly with Python and JavaScript) for the past 2 years.

As an autodidact, I feel I'm lacking knowledge in many of the core principles of software engineering and computer science. I often find myself having great ideas for projects, packages and implementations but find myself running into roadblocks and frustration when trying to express them.

Book recommendations appreciated!
