What I'm looking for

I seek roles that combine education and AI work—designing curricula, building rubrics, ensuring linguistic quality, and contributing to culturally sensitive learning products.

I am a bilingual education professional with a Bachelor's degree in Education and over six years of experience across pedagogy, literacy instruction, and assessment. I combine deep domain knowledge of the Chilean/LatAm education system with practical experience in AI data annotation and rubric design.

I have delivered personalized K-12 curricula and in-home instruction, created custom assessments for Spanish and English literacy, and supported students with diverse learning needs. I graduated with honors and have experience training first-year university students in critical reading and text analysis.

As an AI Data Annotator and QA Specialist, I design evaluative rubrics, perform bilingual quality assurance on AI-generated text, and evaluate content for cultural nuance and linguistic accuracy. I hold certifications including Google AI Essentials and IELTS Academic (Band 8).

I co-founded and directed a nonprofit focused on high-quality transcription, subtitling, and audio/video standards, and I have hands-on experience with data collection, Excel analysis, and tools such as DaVinci Resolve and iZotope RX8.
