As a self-taught developer myself, I too am lacking in these areas and to be quite honest, I think the best way is to continue to self-learn the areas you believe you are lacking in. I've been doing courses over at Udemy myself to learn about algorithms, structuring data and other things. You should go browse the courses over there, you might find something that'll help you out like it did for me.
The problem with studying a CS degree is you're made to learn a lot of what I deem to be useless information. I have friends who have undertaken CS degrees and the general consensus is they learned a lot more when they left university and are quite envious of the fact I took a shortcut in path to employment without any kind of student loan debt. I work with people with degrees mostly and I feel as though I am on the same playing field as everyone else.
