I worked on Portuguese social networks devoted to the support of Spanish students, having translated or localized content from Portuguese to Spanish, and vice versa, and also from English to Spanish. I have familiarity with Spanish spoken in Spain as much as with the "Latino" Spanish, with their differences, sometimes subtle. My knowledge covers slang, swearing and idioms of the Spanish language variants.
My scientific background and IT expertise will assist in the translation and proofreading of technical and formal texts. I can translate and i18n software, apps, and websites to Brazilian Portuguese, but honestly, I will need some research to do it to the Portuguese of Portugal.
