Freelancer Overview

I have more than five years of experience supporting AI and machine learning projects through data annotation, audio labeling, content evaluation and quality checks. At Defined.ai, I worked as a Data Annotation and AI Support Specialist, using tools like Label Studio to label and organize audio data. I made sure the work was accurate, consistent and followed project guidelines. My role also involved checking labeled datasets, identifying errors, reporting data quality issues and collaborating with teams to improve model performance. I have a strong reputation for productivity and accuracy, even when working remotely and under tight deadlines. Along with data labeling, I have helped train AI by writing content, creating prompts and responses, fact-checking and doing evaluation tasks to improve language models. My degree in Information Systems and certifications in Data Annotation & AI Evaluation Fundamentals and AI for Everyone have given me a solid understanding of data workflows, quality control and AI development. I stand out because I pay close attention to detail, think analytically, communicate well in English and follow complex guidelines while delivering quality work that helps train and improve AI systems.
