I wrote a book which would be a good fit for you (math review for adult learners): No Bullshit Guide to Math & Physics. It covers high school math, calculus, and mechanics. Preview here: https://minireference.com/static/excerpts/noBSguide_v5_previ... (I wrote it for students, but adults, and techies seem to really like it too) Available on lulu.com/shop/ and the Amazons.
Also, +1 to other comments that recommend solving exercises/problems. It's very easy to fall into the trap of "I already know this" when reading math, so always good to try things out on your own and, literally, exercise those new knowledge pathways.
This concept map might also help situate you about which math concepts to review: https://minireference.com/static/tutorials/conceptmap.pdf and since you're a coder, you should also look into SymPy which is the best thing since sliced bread when you're learning math, see https://minireference.com/static/tutorials/sympy_tutorial.pd...
