As an example I absolutely love writing applications in JavaScript/TypeScript, but the barrier of entry is exceptionally low, so the quality of work completely sucks. I got out of that. I am also a senior warrant officer in the US Army, which has a really high barrier of entry, and it completely kicks ass.
It sounds like you are young. That means you still have almost unlimited options. If you like math and doing math type things and writing software my best recommendation is to go back to school and work on an engineering masters. Then enter the workforce as a licensed engineer doing actual engineering work with real engineers and real leadership. You can continue to teach yourself software on the side by writing applications to solve for real problems that you have personally.
