Freelancer Overview

I am an experienced AI Trainer and Data Annotation Specialist with a strong background in training, evaluating, and refining large language model outputs. My expertise includes data labeling, prompt writing, and content evaluation across English, Hindi, and Bengali, allowing me to contribute to multilingual AI projects. I have hands-on experience with RLHF frameworks, preference ranking, and micro-tasking for AI/ML datasets, ensuring high accuracy and consistency in annotation. I am skilled in reviewing AI-generated content for instruction adherence, factual accuracy, and contextual relevance, and I am committed to optimizing workflow productivity. My attention to detail and ability to identify data inconsistencies help enhance the quality of training data and overall AI model performance.
