Hi! I'm Dayana Duffus, a native Spanish speaker with a Ph.D. in Economic Sciences and over 15 years of experience in education, 5 in content creation, and  1 in AI training.

I specialize in:

• Data annotation and linguistic evaluation for AI training (Outlier, 2024–2025)
• Spanish-language copywriting with 2,500+ completed projects (2020–present)
• SEO optimization, persuasive writing, and buyer persona analysis
• Cross-cultural communication and educational content design

My content creation experience includes working for clients in fintech, health, travel, and technology, crafting blog posts, landing pages, scripts, and branded content tailored to Latin American and Spanish markets. In AI, I’ve worked on high-quality annotations and evaluations for NLP and generative models, ensuring linguistic accuracy, intent recognition, and cultural relevance in Spanish.

I’m looking for opportunities where I can support AI development and content creation in Spanish, accurately, creatively, and always with attention to cultural context.
