Freelancer Overview

I am currently working in AI training data with Outlier, where I contribute to data labeling, evaluation, and quality assessment tasks that help train and improve AI models. This hands-on experience has deepened my understanding of how AI systems are built and refined. I also hold a Prompt Engineering certification from AWS, which has equipped me with the technical knowledge to craft effective prompts, optimize model outputs, and work confidently within AI-driven environments. What sets me apart is the combination of my practical AI training experience, my certified prompt engineering skills, and my strong background as a Senior Quality Evaluator — where I assessed large volumes of interactions against defined criteria, identified trends, and ensured consistent quality standards. Together, these experiences give me a solid and well-rounded foundation to contribute meaningfully to any AI training data project.
