Freelancer Overview

I have hands on experience in data labeling and AI training , helping refine machine learning models with high quality annotations. From tagging images for autonomous vehicles to training AI for content moderation and natural language processing , I ensure accuracy and consistency in every dataset . Using tools like Labeling, CVAT, and Supervisely , I have worked on projects requiring object detection , semantic segmentation , and sentiment analysis , always meeting strict quality standards. What sets me apart is my keen attention to detail and ability to adapt to different annotation needs . I don't just label data, I understand its impact on AI performance, making sure my work contributes to smarter , more reliable models. Whether collaborating with teams or working independently, I prioritize efficiency and precision, helping clients build AI solutions that truly perform.

High Quality Image Annotation for Autonomous Vehicles

CVATImageEntity Ner ClassificationSegmentation
In this project , I contributed to developing AI models for autonomous vehicles by meticulously annotating thousands high -resolution images . Using boundaries boxes ,polygons, and segmentation techniques , I labeled objects such as pedestrians , traffic signs , vehicles , and lane markings to enhance machine learning model accuracy. The project required a deep understanding of annotation guidelines , attention to detail. and efficient use of labeling tools to ensure high-quality datasets. I collaborated with data scientists and engineers to refine annotation strategies and optimize workflow efficiency. The result was well-structured dataset that significantly improved the performance of computer vision models in real-world driving scenarios.
