RLHF

Freelancer Overview

I am an AI Data Annotator who has 500+ prompt-response pairs annotated using an RLHF-Style project on text, image and video transcript annotation. I do binary safety classification, 5-point Likert ratings (helpfulness, harmlessness, honesty, fluency, instruction following), pairwise preference ranking, bounding box annotation, and time stamp level video review. I have a background in healthcare, where I have worked in patient data processing at Texas Regional Medical Center with 100% audit clearance and identified 45+ discrepancies in healthcare data, all of which are relevant to training medical AI systems. I have been successful in self auditing at 95% consistency and developed a 12-page rubric for annotations based on Anthropic standards for moderation; in addition to this, I am an LLM certified by Google Cloud. What i think is unique about me is that i have a blend of data accuracy in healthcare, and logical courses, and have experience following complicated instructions sequentially, asynchronously. Available 15–25 hours/week.

Labeling Experience

LLM Safety & Instruction Alignment Annotator – Multimodal (Text, Image, Video Transcript)

ImageRLHF

Took the lead in conducting a 3-month, 500+ prompt response annotation project of text, image and video transcript annotation. Transcribed 5 clips of video, performed binary safety classification, 5-point Likert ratings, bounding box annotation (25 images), and pairwise ranking. Followed a 12-page rubric (based on HH/Moderation standards) and reached 95% consistency in the self-audits and recorded 45 edge cases with justifications. All quality measures – blind re-runs, inter-rater checks, precision coordinates – represent production level AI training pipelines.
