Marisa Keim

I am a detail-oriented data specialist with five years of hands-on experience collecting, cleaning, and organizing structured and unstructured data to support AI model development. I focus on delivering high-accuracy annotations across text, images, and categorization tasks to improve model performance.

I collaborate closely with machine learning engineers, coordinating dataset refinements and supplying structured feedback that contributes to measurable accuracy gains. I perform thorough quality-assurance reviews, identify inconsistencies, and ensure data reliability for downstream training and evaluation.

I create and maintain documentation to standardize data preparation and annotation processes, and I am adaptable to new AI tools and platforms. My strong organizational skills and clear communication help me work effectively both independently and within cross-functional teams.

I bring a blend of technical familiarity—basic Python, spreadsheets, and CSV tools—with disciplined workflow management and a commitment to precision that supports robust AI training pipelines.
