Labeling Experience

Domain Expert Annotator – X-Ray Dangerous Goods Recognition

ImageSegmentation

This project involved annotating contraband and dangerous goods in complex, cluttered X-ray images for recognition models. I developed and iterated annotation standard operating procedures to address challenging scenarios, such as occlusions. The annotations provided essential training data for AI detection of prohibited items in security screening. • Labeled contraband in X-ray imagery. • Created and refined annotation protocols. • Handled occluded and overlapping items. • Contributed crucial data for AI model accuracy.

Senior AI Data Annotation Engineer – Autonomous Boarding Bridge Perception Data

ImageSegmentation

In this project, I performed polygon semantic segmentation for aircraft components as part of an autonomous boarding bridge perception system. My responsibilities included accurately labeling complex parts and handling long-tail edge cases such as varying weather and low-light conditions. These annotations were used to create robust ground truth datasets for computer vision model training. • Performed polygon annotation for airplane and bridge imagery. • Accounted for diverse environmental edge cases. • Focused on semantic segmentation of vehicle components. • Ensured high-quality image data for AI use.
