Freelancer Overview

I am an experienced AI training and data labelling specialist with a background in projects where I contributed to a variety of annotation, transcription, evaluation, and linguistic tasks across English and Spanish. My work has involved evaluating large language models (LLMs), generating nuanced text completions, assessing content accuracy, and labelling media and text data for use in AI systems. With a foundation in documentary production and communications, I bring strong research, writing, and linguistic skills in English, Spanish, French, and Italian. I have hands-on experience in transcription, translation, and content labelling for multilingual educational media, as well as in reviewing sensitive government documentation with a focus on detail and compliance. I thrive in remote environments, meet tight deadlines, and adapt quickly to evolving project needs, making me a reliable contributor to AI training initiatives across diverse industries.
