Freelancer Overview

I have hands-on experience in AI training data and data labeling through my work with Outlier, where I contributed to a variety of projects in both Spanish and English. My tasks included mathematical problem-solving, audio transcription and translation, and selecting the most accurate or context-appropriate responses for language models. I also played a key role in content moderation, helping to identify and filter sensitive material to ensure safe and high-quality AI outputs. My strengths lie in linguistic precision, attention to detail, and cross-functional collaboration across diverse project types. I am particularly skilled in working with multilingual datasets and aligning AI responses with cultural and contextual nuances in Spanish. This combination of technical and linguistic expertise enables me to deliver high-quality data that supports the development of responsible and effective AI systems.
