Freelancer Overview

I am a 19-year-old Economics student with strong analytical skills and hands-on experience working with data through Excel, Python, and academic research projects. I have developed a solid understanding of data structures, classification, pattern recognition, and basic machine-learning concepts, which allows me to perform precise data labeling, data cleaning, and quality evaluation tasks across text, images, and structured datasets. I am bilingual (Spanish–English), detail-oriented, and highly disciplined. My background in programming and quantitative analysis helps me follow complex guidelines, maintain consistency, and ensure high-quality annotation for AI training. I am motivated to contribute to cutting-edge AI systems by providing accurate, reliable, and well-structured data.
