Freelancer Overview

I am an experienced data professional specializing in AI training and data labeling, with a strong background in curating high-quality datasets for machine learning models. My expertise spans text annotation, image classification, and semantic labeling, ensuring strict adherence to project schemas and quality benchmarks. I am highly adept at identifying edge cases and maintaining data integrity, which directly contributes to improving model accuracy and reducing bias. Additionally, I have hands-on experience with Reinforcement Learning from Human Feedback (RLHF) workflows, where I evaluate and rank model outputs based on truthfulness, safety, and helpfulness. Working in fast-paced environments, I consistently collaborate with cross-functional teams to refine labeling guidelines and optimize annotation pipelines, delivering high-quality, training-ready data on schedule.
