There’s a pretty good chance your monitor is too low and your keyboard too high relative to one another. Make sure it’s comfortable to type and that you can look directly forward at your monitor while doing so rather than looking downward, which induces slouching and curling your shoulders, which in turn makes it more difficult to sit upright.

Make sure your desktop is at the right height for you to sit with leg joints at right angles rather than adjusting yourself or your chair to a desk that’s at some “standard” height.
