Freelancer Overview

I have hands-on experience working on AI data annotation and quality assurance projects, with a strong focus on improving machine learning model performance. We were contracted by Cruise on driverless systems project, I contributed to the annotation and review of sensor data used to train autonomous models. This involved accurately identifying and labeling objects, road elements, and driving scenarios while adhering to strict guidelines to ensure high-quality datasets that support safe and reliable autonomous navigation. I also worked on ScandIT's shelf item detection project, where I helped train computer vision systems to recognize and classify retail products from shelf images. My responsibilities included identifying products, verifying annotations, maintaining accuracy standards, and ensuring consistency across large datasets. These experiences strengthened my attention to detail, ability to interpret complex guidelines, and commitment to delivering high-quality work in fast-paced AI training environments.
