RLHF

Freelancer Overview

Over the past couple of years I've been working in AI training and data labeling, handling things like text annotation, sentiment analysis, and rating AI responses to help models get better over time. I've used platforms like Scale AI and Labelbox across different projects, from content moderation to helping models understand what people actually mean when they type something. A big part of my work has been RLHF tasks, where I read through AI responses and give feedback on which ones feel more accurate or natural. It's detail-oriented but I enjoy it, and I've gotten comfortable following annotation guidelines closely without sacrificing speed.
