Freelancer Overview

I am a bilingual AI Data Specialist (Spanish native / English C1 certified, EF SET 68/100) with hands-on experience across multiple AI training platforms including RWS, Turing, and Outlier. My work has involved annotating and evaluating AI-generated content, assessing linguistic and cultural accuracy in bilingual outputs, providing structured RLHF feedback, and ensuring data consistency across large-scale labeling pipelines. I bring a strong eye for detail and a solid understanding of quality standards required in AI training workflows. What sets me apart is the combination of my bilingual fluency and my academic background in Sociology, which includes qualitative data coding, SPSS analysis, and structured research methodologies applied in real NGO and field research contexts. This means I don't just label data mechanically — I bring analytical thinking, cultural nuance, and research rigor to every evaluation task. I am fully remote, async-friendly, and available full-time.
