Freelancer Overview

I worked on projects involving text, images, audio, and video data types. Most of my experience has been with Data Annotation Tech, but I also worked with Outlier. This included projects based on segmentation tasks, answering and verifying questions based on LLM outputs or provided content, evaluation and rating AI-generated responses for authenticity, quality, and accuracy; and writing prompts, system instructions, and "golden" responses to help improve LLMs. Work focused on maintaining attention to detail and following guidelines to support the development and refinement of AI systems.
