What I'm looking for

I'm looking for remote AI evaluation or computer vision annotation work where I can apply rigorous quality review, structured reasoning, calibration, and edge-case analysis to improve model performance.

I've supported AI evaluation and data annotation work for Mercor, Handshake, Micro1, and Uber AI, reviewing image, video, multimodal, and structured outputs against detailed quality rubrics.

I identify edge cases, hallucinations, annotation drift, and recurring failure modes; apply severity labels; document clear rationales; and contribute to calibration that improves model quality and reviewer consistency.
