Freelancer Overview

​Senior Data Annotation Specialist & Team Lead ​I am an experienced Data Annotation Specialist with 4 years of expertise in high-volume security datasets and linguistic tasks. My core competency lies in security X-ray analysis (threat detection of firearms, cold weapons, and explosives) and material discrimination, where I consistently processed over 40,000 images monthly. Additionally, I specialize in precise Hebrew audio transcription and OCR, handling approximately 500 files daily with exceptional speed and accuracy. ​Beyond technical execution, I have served as a Team Lead for a group of five annotators, responsible for onboarding new hires and overseeing Quality Assurance (QA). I possess the ability to maintain peak concentration during intensive 7-8 hour shifts and thrive in high-pressure environments, ensuring critical project deadlines are met without compromising data integrity.

Labeling Experience

Computer Vision Data Specialist (OCR & Polygon Segmentation)

Internal Proprietary ToolingImageBounding BoxPolygon

Executed high-precision, character-level annotation for Hebrew Optical Character Recognition (OCR) models. The role required drawing complex polygons to segment individual letters within high-density images containing thousands of characters. I focused on resolving edge cases such as overlapping text and low-resolution characters, ensuring pixel-perfect accuracy to establish high-quality Ground Truth for Computer Vision training.

Data Annotation Team Lead

Label StudioImageBounding BoxPolygon

Automated Threat Detection System (Neural Guard) Contributed to the development of an AI-powered security screening solution designed to automatically detect prohibited items in X-ray imagery. The project involved large-scale annotation of complex luggage scans to train Computer Vision models in identifying firearms, explosives, and cold weapons. As a Team Lead, I managed the data pipeline using the EyeFox platform, ensuring high-quality Ground Truth through rigorous QA and material discrimination analysis.
