Freelancer Overview

I bring over 15 years of experience in data accuracy, verification, and quality assurance, with a strong background in both government data analysis and advanced AI applications. My expertise spans prompt engineering, AI output evaluation, and large language model (LLM) optimization, ensuring that AI-generated outputs are factually accurate, logically consistent, and aligned with safety guidelines. I have hands-on experience developing structured prompt libraries for models like Google Gemini, ChatGPT, and Claude, as well as conducting rigorous data verification and annotation for high-integrity reporting. My work also includes translating complex datasets into actionable insights, managing digital product data for global marketplaces, and educating communities on generative AI. I am skilled in data analysis, pattern recognition, RLHF concepts, and workflow automation, and am passionate about bridging the gap between precise data protocols and innovative AI solutions.
