Freelancer Overview

I have over two years of experience in AI training data annotation and quality assurance, focusing on text-based tasks for large language models (LLMs). I specialize in fact-checking, data accuracy, and prompt refinement, mainly with Spanish-language datasets. Skilled in using remote collaboration tools like Slack and Zoom, I ensure high-quality, context-aware data labeling to improve AI model performance. My work with platforms such as Appen and DataForce involved detailed annotation and review, contributing to better AI responses. Additionally, my freelance digital content creation experience strengthens my ability to optimize and refine prompts. I am detail-oriented, self-motivated, and committed to advancing my skills in AI and data annotation.
