Freelancer Overview

I have done AI training and data labelling work through Prolific: things like annotating data, evaluating content, and giving feedback to help improve AI-generated responses. Each project came with its own set of guidlines, so I got pretty good at following instructions carefully and delivering accurate work. One project that sttod out to me involved reviwing AI-generated text responses and rating them on things like how relevant, clear and safe they were. I'd go through conversational outputs, check them against quality guidlines, flag anything inconsistent and problematic, and write up feedback, aimed at helping improve the perfomance of the AI language model. Over time, I've picked up some skills, like, a sharper eye for detail and the ability to think critically about content quality.
