Freelance AI Trainer – Freelance (Appen, Outlier, Welocalize)
As a Freelance AI Trainer, I specialized in data annotation for text, image, audio, and video projects across multiple platforms and clients. I evaluated outputs from large language models and prompts in both Spanish and English. I collaborated closely with QA teams to ensure guideline adherence and data consistency. • Performed precise tagging, classification, and evaluation of images, audio, video, and text data. • Applied context sensitivity and domain expertise in annotation for multilingual datasets. • Conducted annotation quality assurance and supported guideline development. • Utilized tools including Labelbox, SuperAnnotate, CVAT, Prodigy, LightTag, and Roboflow.
