Tamara K.

AI Data Annotation & Quality Assurance Specialist

Hi, I'm Tamara! I have 4+ years of experience in AI data annotation and quality assurance, working with images, videos, text, and audio. I've worked on a wide range of projects, from image segmentation and video annotation to evaluating AI-generated content and reviewing data for accuracy and consistency. What I enjoy most about this work is that every project brings something different, whether it's learning a new tool, understanding a new set of guidelines, or working with a completely different type of data. WHAT I CAN HELP YOU WITH: • Image Annotation: Bounding boxes, polygons, segmentation, and object labeling • Video Annotation & Evaluation: Video labeling, A/B comparisons, visual quality assessment, and identifying artifacts or inconsistencies • Quality Assurance: Reviewing annotations, identifying errors, and ensuring consistency with project guidelines • Text & Audio Annotation: Text classification, data labeling, and transcription TOOLS: CVAT, Roboflow, Labelbox, Label Studio, Supervisely, LabelImg, VIA, Doccano, and Prodigy. ADDITIONAL TECHNICAL BACKGROUND: I also have a background in Civil Engineering, with knowledge of technical drawings, construction plans, and engineering documentation. I'm comfortable working with technical visual data, including structural defect identification, crack segmentation, and annotation of engineering-related elements. I value clear communication, accuracy, and consistency in my work. I'm comfortable working independently, adapting to new guidelines and tools, and making sure every task is completed carefully and on time. I'm always interested in new projects, especially those involving AI evaluation, image and video annotation, quality assurance, and technical data. Feel free to reach out. I'd love to hear about your project!
