Freelancer Overview

With over five years of experience in AI training and data labeling for multinational organizations, I have developed a strong foundation in the evaluation and enhancement of artificial intelligence systems. For more than two years, I have specialized in assessing large language models (LLMs), generating evaluation scripts, and contributing to their linguistic accuracy and contextual relevance. As a seasoned polyglot fluent in Italian, French, English, and Spanish, I also bring valuable experience in translation and cross-linguistic adaptation. My background includes extensive work in audio recognition and transcription, with a focus on both linguistic and geographic localization. I have also contributed to the analysis and evaluation of map-related data, supporting the refinement of geospatial technologies. My multidisciplinary expertise enables me to bridge the gap between data science, linguistics, and real-world AI applications, ensuring that models are not only technically robust but also culturally and linguistically precise.
