What residency visa would suits me better

I'm brazilian, and I live in Portugal as a university student visa(valid for one more year) . And I want to move to Hungary.

I work remotely for the brazilian court, as an official public servant, but i don't make the 3k euros monthly income requirement for the white visa, but around 1,1k euros. And my intention is to keep working for Brazil and to keep studying IT at my own.

So i'd like to know, please, what visa could apply best for me, in this situation. I have seen some like Visa for Special Activity, or as a student if i get into some IT school, etc, or maybe beggining to give english classes so i can take the entrepeneur visa,etc?

I appreciate your attention.

Thank you. Regards.
