Bio

Brazilian Portuguese specialist, 18 years across games, IT and marketing, now working where language, product and AI meet.

I'm currently International Experience Manager for Brazil at Miro, where I own Brazilian Portuguese end to end. I launched the market for Miro's product release in Brazil, defining tone of voice, style guide and glossary from scratch, and I own prompt design, evaluation and quality governance for PT-BR AI output.


My specialty fields: Advertising, Communication, eMarketing, Games, Internet, Marketing, Mobile and Video Games, including Terms of Use and Privacy Policies.


Workflows where I shine:

- Designing human-in-the-loop AI localization workflows: what the model drafts, where the quality gate sits, and what a human still has to sign off.

- AI output evaluation and governance for PT-BR: deciding what a model can publish and what still needs a human, and building the evaluation that makes that judgement repeatable.


Experience

Owned all Brazilian Portuguese content: ASKfm (Feb 2012 – May 2022), Tumblr (Aug 2016 – Dec 2019), Mint and F3 apps (from Oct 2015).

Games clients: Alawar, Capcom, Codemasters, G5 Games, Hasbro, MyTona, Nintendo, Quantic Dream, Social Point, tinyBuild, TT Games, Ubisoft.

Full PT-BR launches: Under the Waves · Lego Star Wars (all episodes) · GRID 2 Autosport · Not for Broadcast · Seekers Notes · I Am Innocent · Love Choice · Mr. Grinch Christmas Adventure · Challengermode (eSports platform).

LQA / editing / lead translator: Magic: The Gathering · Monster Legends · Dragon City · Idle Miner Tycoon · Shadow Fight · The Secret Society · The Wild Eight.

Genre depth: action/adventure, battle, RPG/MMORPG, hidden objects, time management, puzzles, war, education.

Tech & marketing clients: Apple, Microsoft, LinkedIn, Netflix, Sony, IBM, AWS, Facebook, Skype, Yahoo, CaseWare, Pinnacle.
