Summary

I am a Specialist in Multimodal AI / LLM Training and Search Quality Rating, bringing 10+ years of deep experience in data annotation and quality assurance.

My analytical strength and ability to process complex abstract systems were forged through a Ph.D. in Sociology and a background in Philosophy. This academic foundation provides the strong basis required for interpreting complex guidelines and ensuring high-level quality assurance in data annotation.
