Freelancer Overview

I am an experienced translator, writer, and AI content trainer with over 7 years of expertise in linguistic services and AI data projects. My background includes hands-on work in prompt creation, AI response evaluation, and correction of AI-generated outputs, as well as audio transcription and description for training datasets. Experienced in recording high-quality voice data for AI development, including both scripted narration and spontaneous multi-speaker conversations. Proficient in delivering clear pronunciation, natural intonation, and consistent audio quality in accordance with project specifications and speech data standards.I am fluent in both English and Spanish, which allows me to ensure cultural relevance and linguistic accuracy in multilingual data annotation tasks. I have contributed to projects focused on natural language processing, text quality assurance, and speech recognition model improvement. My strong attention to detail, critical thinking, and independent project management skills enable me to deliver high-quality, reliable training data for AI development.
