Freelancer Overview

I am an experienced AI Training Data and Data Annotation professional with hands-on expertise in image, video, and LiDAR annotation for machine learning and computer vision projects. My work has involved annotating 2D and 3D LiDAR datasets, classifying AI training images, labeling soccer footage for sports analytics, and annotating aerial imagery for geographic and urban planning applications. I have consistently ensured high-quality datasets through detailed quality assurance processes, data verification, error correction, and adherence to strict project guidelines and timelines. In addition, I have collaborated closely with data analysts, quality analysts, and engineers to support the development of robust and reliable AI models. Beyond annotation, I bring strong analytical and technical capabilities in AI and data operations, including extracting, organizing, matching, and reconciling large datasets from multiple sources to improve accuracy and accessibility. I have experience developing and fine-tuning AI models using no-code platforms and contributing platform feedback to improve system functionality and efficiency. My strengths include attention to detail, adaptability, time management, and the ability to manage multiple projects simultaneously while maintaining high-quality standards. Combined with certifications in ALX Virtual Assistant and ALX AI Career Essentials, I offer a strong foundation in AI training data workflows, data quality management, and collaborative problem-solving.
