What I'm looking for

I seek roles where I can apply AI training, moderation, and annotation expertise on long-term LLM projects, with opportunities for leadership and impact.

I am a Senior Quality Analyst and AI data specialist with extensive experience in AI training, content moderation, translation, transcription, data collection, and annotation. I have worked on long-term LLM projects and served as a Project Manager and social media/ads evaluator for large technology companies, bringing a practical blend of quality assurance and operational oversight.

With over eight years in human resources, finance, and customer service, I offer proven skills in multilingual translation (English/Portuguese, Spanish/Portuguese, French/Portuguese), audio/video transcription, UHRS tasks, and advanced Office suite proficiency. I am results-driven, detail-oriented, and committed to improving model performance and content quality through rigorous evaluation and annotation practices.
