Freelancer Overview

I possess a powerful and current skillset highly relevant for the modern tech industry. I have dedicated, recent training in Prompt engineering from institutions like Vanderbilt University and Google, which makes me adept at optimizing Large Language Models (LLMs) and generative AI systems. I couple this technical knowledge with hands-on training in Data Annotation, including practical experience with the CVAT: Image & Video Data Annotation Platform and foundational concepts in Machine Learning, Algorithms, and Natural language processing. Additionally, my fluency in both English and Spanish is a critical asset for high-accuracy linguistic tasks, multilingual content validation, and prompt testing. This combination of specialized AI training and bilingual proficiency is further bolstered by my 20+ years of experience as an audio recording engineer with programming expertise in digital audio workstations. I am well-positioned for technical roles focused on data quality, AI workflow optimization, and model training.
