What I'm looking for

I'm looking for remote work in AI/LLM evaluation, language quality, content QA, translation review, or guideline-based data annotation, where I can apply Brazilian Portuguese expertise, careful analysis, and structured feedback.

I've reviewed AI-generated subtitles for UFPA research videos and evaluated AI/LLM responses for factual accuracy, hallucinations, coherence, instruction adherence, translation accuracy, and contextual relevance. I also completed English–Portuguese translation projects and proofread academic writing with close attention to grammar, clarity, and natural phrasing.

I bring operational leadership from running Datashow Express, directing an agricultural cooperative, and supervising a sales team. I'm focused on guideline-based annotation, content QA, and Brazilian Portuguese language quality.
