[Honguito]

Hi zFranco I read your post. You already have a Licenciatura with some Math and experience in SWE.
If you are interested in learning and getting a good master's degree, you can check OMSCS GaTech:

A lot of people get accept without a CS degree so you should be fine because you have Math on yours. It will cost you around 7k and it will take you time so per year won't be too much.

Otherwise, you can do TESU, they will take a lot of credits from your degree, 30 elective credits plus GE credits. You can do it quick there but for the same money you can get a master in a top university and learn a lot.
