Data Annotation Specialist
Feb 2022 - Present • 4 yrs 3 mos
I have been working as a freelance Data Annotation Specialist since 2022, providing high-quality data labeling and annotation services to clients and AI companies across the USA, UK, Canada, and Australia. Over the years I have built strong expertise in preparing clean, accurate, and well-structured training datasets for machine learning and artificial intelligence models. My data annotation services cover a wide range of tasks including image annotation, object detection labeling, bounding box drawing, polygon segmentation, landmark annotation, text classification, sentiment analysis, named entity recognition, intent labeling, and audio transcription. I work with both simple and complex datasets and always follow client guidelines precisely to ensure the highest quality output. I have worked with clients from diverse industries including autonomous vehicles, healthcare AI, e-commerce product recognition, natural language processing, social media sentiment tracking, and chatbot training. Whether the project involves annotating thousands of images or labeling large text datasets, I deliver consistent and accurate results every single time. Tools and platforms I have experience with include Labelbox, Scale AI, CVAT, Appen, Lionbridge, DataLoop, and various custom client annotation platforms. I am quick to adapt to new tools and guidelines provided by clients. What sets me apart is my strong attention to detail, fast turnaround time, and ability to handle large volume projects without compromising on accuracy. I understand how critical clean and correctly labeled data is for the performance of AI and ML models, which is why I treat every annotation task with the highest level of care and precision. I am available for both short-term tasks and long-term ongoing annotation projects and always maintain open, clear communication with my clients throughout the project.
