Freelancer Overview
With hands-on experience in high-precision video annotation, I contributed to the Poland Soccer Project by annotating jersey numbers and tracking player identities using RespoAnnotationApp (Autocom, OCR, All mode). I verified algorithmic outputs and manually identified players through visual features such as hairstyle, facial hair, sleeve length, cleats, tattoos, and field positioning. Working in multi-user workflows with GCP sync, I delivered structured files (, , ) and achieved over 98% QA accuracy, strengthening expertise in sports analytics and AI training data.
Building on this, I worked on Project Tiramisu for self-driving cars, annotating lane lines, road boundaries, centerlines, arrows, and traffic signs using GT Studio, 2D, and 3D views. I applied attributes including color, type (solid/dashed), visibility (camera/lidar), and lane usage (HOV, bus/taxi, turn lanes). I validated 3D annotations to ensure lane lines touched the ground correctly without zigzag or floating errors, producing structured outputs with high QA accuracy. Skilled in 2D/3D annotation, attribute management, and quality assurance, I deliver clean, reliable datasets for autonomous driving AI.
