Freelancer Overview

I am an experienced data annotator and online data analyst with a strong background in evaluating search engine results and comparing AI-generated responses for quality, safety, and factual accuracy. My work at Mindrift involved hands-on annotation tasks that contributed to the improvement of recommendation systems and machine learning models. In addition to my technical skills, I have a proven track record as a freelance writer and transcriber on Upwork, where I consistently delivered high-quality content and transcription projects with a 90% job success score. My expertise in Microsoft Office, quality control, and research, combined with my academic background, enables me to approach data labeling and annotation tasks with precision and attention to detail. I am passionate about leveraging technology to solve real-world problems and am eager to contribute to impactful AI training data projects.
