Freelancer Overview

I am an experienced data annotation and AI training data specialist with a background in finance, banking, and advanced AI projects. My work spans high-precision labeling and quality assurance for text, audio, and image datasets, with a focus on optimizing machine learning models for natural language processing, computer vision, and financial domains. I have led data enrichment initiatives on projects like Project Nidra, applying expert-in-the-loop feedback, RLHF, DPO, and chain-of-thought reasoning to improve generative AI reliability and reduce hallucinations. My experience includes complex entity recognition, sentiment analysis, intent classification, and rigorous QA, consistently maintaining 98–99% accuracy. I am skilled at collaborating with engineers and data scientists to translate domain-specific requirements into actionable annotation guidelines, and I bring a strong commitment to ethical data handling, compliance, and operational excellence.
