Freelancer Overview

I am a detail-oriented AI training and data operations professional with hands-on experience in data annotation, content evaluation, and supporting AI-assisted workflows, primarily focused on NLP and text-based tasks. I have worked extensively with tools like ChatGPT, Google Docs, and Notion to label, review, and refine AI-generated content, ensuring outputs meet stringent quality and guideline standards. My background includes structured research, fact-checking, and documentation, as well as building and optimizing AI workflows for text generation, summarization, and prompt evaluation. I am committed to ethical AI practices, accuracy, and continuous improvement, and thrive in remote, collaborative environments where high attention to detail and methodological work styles are valued.
