Freelancer Overview

I bring 4 + years of hands-on experience curating, labeling, and auditing datasets for language, vision, and policy-compliance projects. My core work has focused on enforcing Meta and Google advertising standards, where I reviewed thousands of multilingual ads, tagged sensitive content, and produced gold-standard datasets that now train automated policy-violation detectors. In parallel, I have evaluated large-language-model (LLM) prompts and completions in English, Portuguese, and Spanish—rating fluency, factuality, and safety, and writing high-quality reference answers that improve model alignment. I’m equally comfortable annotating text, images, or mixed-media assets; building clear labeling guidelines; and coordinating distributed teams through agile tools. This blend of multilingual capability, policy expertise, and meticulous QA enables me to deliver reliable, bias-aware training data that accelerates AI performance across industries.
