Freelancer Overview

I am a detail-oriented data science student with hands-on experience in data annotation, AI training, and audio transcription for AI enhancement. My work with CrowdGen involved evaluating ad quality and relevance, as well as annotating and labeling data to improve machine learning models. At Sigma AI, I contributed to refining AI systems through accurate audio transcription. I am proficient in tools such as Python, SQL, and Advanced Excel, and have a solid foundation in machine learning, programming logic, and data analysis. I thrive in collaborative and fast-paced environments, and I am eager to apply my skills to support high-quality AI training data projects.
