What I'm looking for

I'm looking for remote AI training, data annotation, or data quality work where I can evaluate outputs, improve data accuracy, follow detailed instructions, and contribute to reliable AI systems.

I evaluate AI outputs for alignment with intended results, identifying hallucinations and applying careful fact-checking across DataAnnotation.tech, Outlier, and Remotasks.

I annotate image and visual data to help AI models understand content, and I perform rubric scoring for consciousness, truthfulness, and harmlessness.

I also run automated and manual SQL audits to find duplicate records, missing fields, and formatting errors in raw data.

Alongside quality work, I train team members on data-entry practices, maintain documentation, and respond to technical support tickets. My MSc in Business Analytics supports my structured approach to data and AI evaluation.
