Freelancer Overview

I have extensive experience in AI training data creation and data labeling, particularly in Natural Language Processing (NLP) and Machine Learning (ML) model development. My expertise includes data annotation for text, image, and speech recognition, with a strong focus on entity recognition, sentiment analysis, intent classification, and speech-to-text validation. I have contributed to training datasets for large language models (LLMs), chatbots, virtual assistants, and AI-driven automation systems. Additionally, I am skilled in data quality control, bias mitigation, and dataset optimization to improve AI model accuracy and fairness. My work extends beyond annotation to AI model fine-tuning and prompt engineering, ensuring that AI systems perform effectively in real-world applications. I am experienced in using industry-standard tools like Labelbox, Prodigy, and Amazon SageMaker Ground Truth for efficient data labeling workflows. My ability to analyze complex datasets and refine training methodologies makes me a valuable asset in developing high-performing AI solutions.
