Yamalith Díaz

I’m an AI evaluator and QA specialist with 4+ years in high-volume content review and trust & safety operations, focused on accuracy, judgment quality, and clear feedback. I’ve worked across real estate and leasing domain prompts as well as high-sensitivity moderation workflows.

In my AI Domain Expert role, I evaluate model responses using a 6-dimension rubric—Instruction Following, Truthfulness, Correctness, Writing Quality, Verbosity, and Overall Quality. I also run comparative pairwise evaluations, selecting preferred outputs and writing detailed justifications per dimension, then stress-test reasoning with domain-specific prompts.

Previously, I was promoted from line moderator to QA specialist at Teleperformance/ByteDance (TikTok), where I audited policy compliance, maintained 97–100% accuracy, and consistently ranked top performer. I analyzed edge cases and identified policy gaps in queues (including Hate Speech, Graphic Content, and Violent Behavior) and delivered calibration feedback with me as the SME point of contact for escalations.

I bring strong operational discipline from moderation and content quality roles, reviewing 1,000–1,300 items/day and supporting onboarding and policy Q&A for team members. I’m open to AI evaluation, RLHF annotation, data quality, and Trust & Safety roles where rubric-based quality and continuous calibration make measurable impact.
