Available for long term AI Training, Language Evaluation and Data Annotation projects. Hi! I'm a multilingual AI Training and Language Specialist with hands on experience in AI model training, prompt evaluation, multilingual data annotation, translation, and content review. I work professionally in Italian, English, and Brazilian Portuguese, helping improve AI systems through high quality language data and detailed evaluations. Over the past several months, I've worked on a wide variety of AI training projects involving prompt writing, response evaluation, ranking, annotation, rewriting, translation, and quality assurance. Before moving into AI, I worked as an English teacher for Italian students for over two years. This experience strengthened my understanding of language, communication, and cultural nuances across different audiences. I'm used to jumping between different types of AI projects, adapting quickly to new guidelines, and learning new workflows as I go. Having worked with multilingual tasks in Italian, English, and Portuguese, I'm comfortable handling everything from response evaluation to translation, annotation, and content review. Services I provide: • AI Training • Prompt Writing & Evaluation • Data Annotation • Response Ranking & Quality Review • Translation (Italian • English • Portuguese) • Localization • Proofreading & Editing • Content Review • Multilingual Language Evaluation I'm always excited to contribute to projects where language and AI come together, and I'm looking forward to working with you!
