RLHF

Freelancer Overview

I’m a senior data annotator and AI rater with 4+ years of hands-on work. I build clean, consistent datasets for NLP, vision, and chat models. I’ve delivered projects with Outlier AI, DataAnnotation Tech, Stellar AI, and Surge AI, covering labeling, prompt writing, RLHF reviews, and safety red teaming. My toolkit includes Labelbox, Surge, SuperAnnotate, Scale/Nucleus, and well-structured spreadsheets. I write clear guidelines, run QA audits, and lead small pods when needed. I track inter-annotator agreement, spot edge cases early, and tighten rules so quality stays high. I’m comfortable with span and entity tagging, sentiment and intent work, dialogue ratings, content policy tests, code and reasoning tasks, and detailed rubric design. I move fast, hit deadlines, and keep noise low while protecting data integrity.
