There are various approaches to becoming a good Software developer, and to be honest I think math fundamentals are as important as algorithmic foundations, which you can probably also pick up quite well with your background. The one major difference (it is a tendency, not absolute) between software devs who came from CS and those that changed careers into it is a deep passion for computers and how they work. Look at HN, there's a lot of talk about Lisp, Assembly, C etc. although few people actually need it for their jobs. Dealing with these things usually comes from a place of passion more than a place of necessity, and they do make you a better dev, too. A book I can warmly recommend if you want to see how deep your own interests go is "Principles of Programming languages" by MacLennan. He takes a historical approach, explaining the design principles of programming languages by looking at historically game-changing programming languages that few people still use today. The exercises get progressively more complex, and the last exercise is to design and implement your own programming language, a task I haven't yet done myself.
