Freelancer Overview

I am an experienced AI data labeler and annotation specialist with over two years of hands-on work curating, annotating, and validating datasets for machine learning and NLP projects. My background spans text, document, and structured data labeling, as well as quality assurance and metadata management for AI-driven systems. I have a strong track record in evaluating AI-generated outputs, providing structured feedback, and maintaining high data quality for production environments. I am proficient in Python, Node.js, LangChain, and workflow automation tools like n8n and Zapier, and have contributed to projects involving document processing, AI search and retrieval, and data validation for analytics. My attention to detail, analytical mindset, and ability to follow structured guidelines help me consistently deliver accurate and reliable training data for AI models. I am eager to contribute my expertise to remote teams focused on data labeling, annotation, or AI quality evaluation.
