Available to hire
I’m Marta Rejane Claudino, a Brazilian Portuguese native with a strong focus on linguistic quality assurance, localization, and gaming QA. I specialize in LQA/FQA, language testing, data labeling, and AI-assisted evaluation, with a track record of improving translation consistency, cultural relevance, and product readiness across multilingual projects. I enjoy solving linguistic and UX challenges in software, games, and AI-infused workflows, always aiming to deliver accurate, natural, and culturally appropriate results.
Over the years I’ve collaborated with global teams (Lionbridge, PTW/Side, and freelance clients) on large-scale game projects, AAA releases, and AI data tasks. I thrive in fast-paced environments, meticulously document issues, and value clear communication with developers to ensure high-quality experiences for players and users alike.
