AI Trainer at Welo Data evaluating LLM quality and detecting hallucinations across generative AI outputs.

Greece
Message

At Welo Data, I evaluate large language model outputs for factual precision, reasoning, consistency, tone, and safety. I also identify hallucinations and logical errors, using prompt refinement and Leap Space diagnostic tools.

At the University of Thessaly, I completed a qualitative research monograph on slam poetry, analyzing 34 recorded performances and conducting five expert interviews. My experience also includes customer operations, confidential intake coordination, and research volunteering with the Act4Lang initiative.
