What I'm looking for

I’m seeking a role in AI data training and evaluation.

At DataAnnotation.tech, I evaluated and annotated AI-generated responses for accuracy, clarity, relevance, and logical consistency. I applied annotation guidelines and scoring criteria to classification, ranking, and comparative evaluation tasks.

At Scribie, I validated transcription outputs against source audio, flagged incorrect or misaligned segments, and maintained 90%+ accuracy while processing 50+ audio files per week.

As a freelance reviewer with QA World, I evaluated audio transcripts against predefined quality standards and provided detailed feedback to improve dataset quality. I’m seeking a role in AI data training and evaluation.
