If you have your masters, you could try teaching as an adjunct at a local university at night. Pay isn't bad (relative to the amount of work) and you can stay in the field. Rewarding work, and in some state/provincial systems you can even earn a pension. I get speaking isn't your thing, so that might be an impediment, but maybe it's less of an issue in a more intimate setting

To be honest you don't even have to go to universities or schools. Just offer tutoring from the field or around the field you're in. There's a lot of money to be made like this, especially since math in school is fairly easy to teach for someone with comp-sci degree.
