Freelancer Overview

I am an experienced AI data annotation specialist with over 7 years of hands-on work in developing high-quality datasets and evaluating AI models. My background includes a PhD in Computer Science with a focus on AI, and I have contributed to the entire AI pipeline—from annotating multimodal datasets (images, text, and AI-generated responses) to training and evaluating large language models. My expertise spans computer vision projects, such as object detection for autonomous vehicles and medical imaging, as well as natural language processing tasks and reinforcement learning with human feedback (RLHF). I am skilled in using tools like Labelbox and CVAT, and have a strong track record in quality assurance, dataset validation, and ensuring data accuracy for both research and production environments. My work is supported by advanced certifications in AI model evaluation, ethics, and data labeling.

Assisted with large-scale annotation and evaluation tasks for training and fine-tuning large language models. The tasks involved evaluating the responses generated by AI, grading the responses based on their accuracy, reasoning, safety, and ability to follow instructions. I helped with reinforcement learning with human feedback (RLHF) by writing and evaluating prompt-response pairs for fine-tuning the models.
