Finish your degree, doesn't matter if it's Math and Econ, lots of these majors get into software as a profession.

If you have experience with SQL and are good at it you can find work everywhere with that alone.

If you want to become more full stack learn one of the more popular web app front ends, however I will note that I've used SQL for nearly three decades, the only other tech that I can think of that existed in 1992 and is still fairly mainstream today would be shell scripting and PHP. All the modern web tech, javascript-y stuff is shifting sand and it will change or be replaced as fast as you can become competent at it. It's exciting at first, then frustrating, then demotivating. Or at least that's how it seems to me.
