Antonia Roco

I am a detail-oriented freelance data annotator and language specialist with a Bachelor's degree in Midwifery from Universidad de Valparaíso. My clinical training and thesis work — which involved translation, correction, and peer review of English-language research papers — have sharpened my analytical rigor and ethical approach to data and text.

I perform AI model evaluation, prompt optimization, and content review in English, applying linguistic judgment, logical consistency checks, and quality control to improve model performance. I have experience translating and editing academic studies from English to Spanish and ensuring high standards of grammar and coherence.

I am a fast learner comfortable working remotely and collaboratively on text-based projects, available 20–30 hours per week with a flexible schedule in the GMT-4 / Chile time zone. I seek roles that value precision, language expertise, and contributions to high-quality AI training data.
