Freelancer Overview

I have experience in quality-focused tasks such as functional, regression, smoke, and load testing, which have strengthened my attention to detail and ability to follow strict guidelines—skills that are essential for accurate data labeling and AI training data work. I am comfortable handling structured datasets, identifying errors, and ensuring consistent, high-quality outputs. With a Computer Science background and ongoing studies in Artificial Intelligence, I understand the importance of clean training data in model performance. I learn quickly, adapt to new annotation tools easily, and maintain accuracy even in repetitive tasks.
