What I'm looking for

I seek remote roles on collaborative, international teams where I can apply annotation, QA, and ML model-training skills to improve dataset quality and model performance.

I am an AI model trainer and content reviewer with hands-on experience annotating and validating large text and audio datasets to improve model reliability and reduce bias.

I have strengthened dataset quality and performed structured QA that reduced annotation error rates by 20%, and I have annotated 10,000+ English and Spanish samples for sentiment and NLP tasks.

My background includes information systems education and practical skills in Python, SQL, TensorFlow, PyTorch, and data-preprocessing tools, plus experience building dashboards and queries to accelerate reporting.

I thrive in remote, cross-cultural teams, reliably meet deadlines on multilingual projects, and seek to contribute technical proficiency and disciplined QA practices to global ML initiatives.
