Freelancer Overview

I am an experienced contributor to mathematics-focused AI projects, including reinforcement learning from human feedback (RLHF), where I curated and refined datasets to enhance model accuracy and alignment with human understanding. In addition, I have extensive expertise in audio-focused AI, including recording and annotating audio data for model training. My responsibilities have also included serving as both a reviewer and senior reviewer, ensuring annotation quality, consistency, and adherence to project standards. Passionate about advancing AI applications, I aim to bridge the gap between cutting-edge technology and meaningful, human-centered solutions.

The project is an RLHF project on Outlier AI where I try to prompt an LLM with mathematical problems that will make the model fail in a certain aspect. After the model fails I have to correct the response and make it perfect.
