Bio

I'm a translator working from English and Spanish into Brazilian Portuguese, specializing in games, apps, and design.


1) Experience:


Video game translation and proofreading:


Goodboy Galaxy

Exploration platform game – Nintendo Switch, PC


– Brazilian localization praised by a YouTuber as “one of the best indie game translations out there”

– A challenging project due to limited space in the dialogue box

– I reported several typos in the English text and a few bugs


Title under NDA

Action RPG with classic cartoon characters and a basketball star – Mobile, PC


– Translated over 549,000 words


Title under NDA

Action RPG with world-famous superheroes – Mobile


– I fixed a consistency issue where some character names were translated and others weren’t. After careful research, I corrected 31 mistranslated names.


Other titles:

• Casual sports and simulation game, official video game of the Olympic Games – Mobile, PC

• Game based on a classic property trading board game – Mobile

• Match-3 decoration game – Mobile

• Strategy MMO game based on a sci-fi franchise – Mobile, PC


Brands that trust my work:

• The Olympic Games

• Two space franchises with huge fan bases

• Classic cartoon characters who shared the court with basketballs stars

• Some famous superheroes (I even named a minor original character)

• A classic property trading board game


2) Feedback on my work. Brazilian YouTuber Tulio Santos reviewed my localization of Goodboy Galaxy:


"This is more than just a basic translation, it’s an amazing localization. The jokes, puns, and meme references make the characters and NPCs even more charming.


It’s one of the best indie game translations out there.


It’s rare to see this level of effort in localization. Instead of translating word for word, the translator carefully adapted the text for Brazilian Portuguese."


3) CAT tools: SDL Trados Studio and Smartcat. I'm open to using other tools.


4) Courses:


• Literary translation

• Introduction to CAT tools

• Subtitling

• Introduction to regex


5) I studied design at university and worked in the field for a few years, so I'm familiar with design software and content.
