You mean in addition to, I hope.

If you want a developer’s career, studying CS in college is the best way to get there. Full stop.

If you have the time, financial, and emotional resources (school isn't stress free!) then having a minor or double major in a specialized field will (obviously) make you more attractive as a candidate for a development role in that field.
