Freelancer Overview

I am a data annotation specialist with over five years of experience providing training data for AI in computer vision, autonomous systems, and natural language processing (NLP). With proven reliability on deliveries and 98%+ accuracy, I am an expert in 2D/3D/4D annotation, LiDAR point cloud labelling, semantic segmentation, and video annotation. I have worked on AI platforms such as Toloka, Scale AI, Oasis Outsourcing, and Avala AI, managing annotation and quality assurance to ensure the accuracy, consistency, and reliability of training datasets. I am not only a labeller, but also adept at evaluating prompts for different NLP models. Additionally, am skilled in using various annotation portals like Labelbox, CVAT and Supervisory. Lastly, I am effective at working in remote, time-bound settings. By mastering the creation of clean and contextualised data which boost model performance and real-life applicability, it is important to possess some technical skills.
