What I'm looking for

I'm looking for a hybrid or remote role where I can improve NLP and generative AI systems through model evaluation, linguistic data quality, training-data optimization, and collaboration with interdisciplinary teams.

I'm a computational linguist focused on improving generative AI systems through model evaluation, linguistic data quality assurance, and training-data optimization.

At IA Generativa y PLN, I analyzed AI-generated outputs, validated linguistic datasets, structured training data for NLP applications, and developed quality guidelines and documentation alongside interdisciplinary teams.

My master's studies in Language Processing and Applications of Artificial Intelligence to Linguistics cover NLP, machine learning, deep learning, large language models, text mining, data analysis, and chatbot development.

Alongside AI work, I've supported multilingual learners as a Spanish Language Assistant in Germany, adapting structured materials and using observation and feedback to support individual learning. I bring native Spanish, C1 German, and C2 English to international work environments.
