Freelancer Overview

I am a detail-oriented professional with hands-on experience in data annotation, content evaluation, and AI training data preparation. My work with Welocalize, CrowdGen (Previously Appen), and Mercor has allowed me to develop strong skills in labeling data for machine learning, evaluating search data relevance, and generating high-quality spoken descriptions for image-based projects. I am adept at following complex guidelines, adapting to evolving standards, and ensuring both productivity and quality in remote environments. My technical skills include proficiency with R Studio and BORIS software, and I am comfortable collaborating with AI researchers and QA teams to improve data quality. With a background in ecology and multidisciplinary science, I bring analytical thinking, research expertise, and strong communication skills to every project.
