Freelancer Overview

I am a Data Labeling Specialist with 2 years of experience supporting AI and machine learning projects for both domestic and international clients. My work spans image, text, audio, and video annotation, with hands-on expertise in labeling tools to ensure high accuracy and efficiency. I have contributed to projects in domains such as autonomous vehicles, retail analytics, smart monitoring, and NLP applications like intent classification, entity extraction, and OCR for administrative documents. I am skilled at collaborating with Data Engineers, QA, and Product teams to optimize annotation processes, standardize guidelines, and improve data quality—resulting in measurable reductions in errors and increased review efficiency. I am passionate about further developing my skills in Data Operations and QA to help deliver reliable, high-quality training data for advanced AI systems.

Labeling Experience

AI Image Annotation for Autonomous Driving Object Detection

CVATImageBounding BoxPolygon

This project focused on annotating large-scale image datasets for training computer vision models in autonomous driving systems. I was responsible for accurately labeling various road objects including vehicles, pedestrians, traffic lights, traffic signs, bicycles, and road markings using bounding boxes and polygon segmentation techniques.
