Freelancer Overview

I am a dedicated AI Trainer and Data Annotation Specialist with hands-on experience training and evaluating large language models (LLMs) and chatbots across leading platforms like Appen, Outlier, and Scale AI. My expertise spans high-precision data labeling, text classification, sentiment and intent annotation, and multilingual dataset handling. I excel at detecting model hallucinations, bias, and ethical issues, ensuring AI outputs are contextually accurate and safe. With a strong foundation in data science—including data cleaning, preprocessing, and exploratory analysis using Python—I consistently deliver reliable, high-quality training data and actionable feedback that improve AI model performance. My remote work experience has honed my adaptability, attention to detail, and ability to maintain rigorous quality standards in fast-paced AI projects.
