Freelancer Overview

I have a strong background in data management and analysis, with hands-on experience building and structuring databases for research projects, including organizing 30 years of crop and climate data and performing correlation analyses. My education in Physics, Mathematics, and Agroforestry Sciences has given me a solid foundation in logical thinking, statistical analysis, and understanding complex datasets. I am skilled in tools such as Microsoft Excel, R-Studio, QGIS, Python, and SQL, and have experience interpreting charts and graphs. My attention to detail, fast typing, and effective communication skills—honed through years of customer service roles in both English and Spanish—make me well-suited for data labeling, annotation, and AI training data tasks. I am proactive, a quick learner, and thrive in roles that require accuracy, organization, and analytical thinking.
