Freelancer Overview

I am passionate about AI and data quality, with hands-on experience curating, annotating, and analyzing diverse datasets—including text, audio, image, and video—to support machine learning model training. My background includes working as an AI Tutor and Advanced AI Data Trainer, where I evaluated and refined datasets, performed quality assurance, and provided structured feedback to enhance model reasoning and accuracy. I am skilled at identifying patterns, ensuring data consistency, and optimizing training pipelines, especially in multilingual and multimodal contexts. My technical toolkit includes Python, Pandas, SQL, Java, and tools like Git, Docker, and PowerBI, and I have practical experience in building projects such as a movie recommendation system and a CRM platform. I thrive in collaborative environments, adapt quickly to new technologies, and am committed to delivering high-integrity data for AI development.
