Freelancer Overview

I have contributed to the Humanity’s Last Exam project through the Outlier.ai platform by Scale AI. In this initiative, I developed PhD-level prompts (sometimes involving an image) in the fields of psychology and neuroscience designed to challenge the most advanced large language models. For each prompt, I also provided a detailed, expert-level step-by-step solution. In addition to content creation, I served as a senior reviewer, evaluating the quality and accuracy of prompts, solutions, and answers submitted by other domain experts. I also participated in the Music Match project on Outlier.ai, where I analyzed short music clips and generated detailed descriptions identifying the genre, vocal characteristics, language of the lyrics, emotional tone, instrumentation, transitions, and overall audio quality.
