What I'm looking for

I'm looking for AI data quality or evaluation work where I can apply rigorous review standards, identify recurring data issues, improve annotation guidelines, and deliver clear, actionable feedback in a distributed team.

At Otaku Hugo, I review annotated text, audio, images, and video against quality standards and rubrics, documenting defects and required corrections for large-scale AI data projects. I analyze sentiment, intent, speaker context, and emotional cues to improve caption clarity and label accuracy.

Previously at Emzor Pharmaceuticals, I monitored production quality against GMP standards, trended quality data in Oracle ERP, and used risk-based thinking to resolve deviations and strengthen review checklists.
