Good luck first of all. Sounds like you've done well for yourself thus far. If you got the savings, I would say go for it and take the time to learn. I don't know how helpful the math for computer science course will be but understanding various algorithms is useful for general knowledge and especially for interviews. Once you know basic algorithms, start on cracking the coding interview, hackerrank etc. Lastly, I would say the grass is always greener on the other side, so don't disregard all you have accomplished and all that you will continue to do. If you think you will enjoy a job at a top company, go for it, but don't do it because you think what you are doing is inadequate.
