How to gain experience if i don't have a job?

[deiry]

I just graduated as a Software Engineer and thanks to my thesis I decided to focus on health care using ML techniques, at this time, I am looking for work in this area, it happens that in my country (Colombia) there are only jobs to advise financial companies, marketing, and in other countries I have been rejected for not having much experience. I would appreciate if you give me some advice to keep growing!!!
