What I'm looking for

I'm looking for AI data quality or evaluation work where I can review multimedia datasets, improve annotation standards, identify recurring quality issues, and provide structured 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 so contributors can resolve issues clearly. I track recurring error trends across weekly batches of 1,000+ data assets and help refine evaluation criteria and QC checklists.

Previously at Emzor Pharmaceuticals, I monitored production quality against GMP standards, investigated deviations, and used Oracle ERP trending to highlight recurring issues. I bring risk-based quality thinking, strong written English, and disciplined attention to detail to large-scale AI data projects.
