What I'm looking for

I'm looking for remote AI data annotation or training-data work where I can apply detailed guidelines, validate datasets, improve data quality, and support machine learning development.

I've supported AI and machine learning projects at iMerit, Outlier AI, and Remotasks through accurate data annotation, labeling, validation, and quality assurance.

At iMerit, I annotated, categorized, and validated large AI training datasets, reviewed and corrected annotations, and documented findings to support process improvements and model development.

At Outlier AI, I evaluated AI-generated outputs, performed text annotation and factual verification, and corrected inaccurate labels to improve training-data reliability.

With a Bachelor of Science in Statistics, I bring analytical thinking, careful guideline compliance, and a commitment to quality while delivering remote work under deadlines.
