Freelancer Overview

I am an experienced AI training specialist with a strong background in developing and delivering data labeling and annotation frameworks for diverse organizations. My work spans designing modular, scalable curricula for AI model alignment and evaluation, with a focus on ensuring high-quality training data across domains such as STEM education, workflow optimization, and digital identity. I have led projects that include AI curriculum development, the creation of robust rubrics for data annotation, and hands-on workshops in applied technologies like 3D printing and prototyping. My interdisciplinary approach allows me to bridge technical expertise with clear, effective training—empowering teams to produce accurate, reliable datasets for machine learning and AI applications.

Experience Demo: Leveraged STEM and interdisciplinary expertise to train Large Language Models (LLMs) through RLHF (Reinforcement Learning from Human Feedback). Task Mastery: Created complex multi-step reasoning prompts, performed fact-checking against authoritative sources, and conducted "Red Teaming" to identify model hallucinations or safety violations. Ranking & Evaluation: Ranked model-generated responses based on strict rubrics for accuracy, tone, and helpfulness, often providing detailed justifications for "Preferred" vs. "Not Preferred" outputs.
