Freelancer Overview

I have hands-on experience in AI training data and data labeling, with a strong focus on Optical Character Recognition (OCR) and computer vision annotation for Document AI systems. I worked on large-scale OCR projects involving word-, line-, and paragraph-level annotation, including drawing precise bounding boxes, transcribing multilingual and handwritten text, distinguishing scene versus overlaid text, and applying complex layout and semantic grouping rules. My work included reviewing and correcting AI-preannotated outputs in strict accordance with detailed guidelines and quality standards. In addition to annotation, I was selected to participate in audit and review queues, where I evaluated annotations produced by other vendors, identified guideline deviations, and applied corrections to ensure full compliance. My submissions received a Strong Pass QA rating, reflecting high accuracy, consistency, and attention to detail. I am experienced in QA-driven workflows with full audit coverage, productivity benchmarks (AHT), and zero-tolerance error criteria, and I reliably deliver high-quality labeled data suitable for training and validating machine learning models.

OCR Image Annotation & QA Review (Document AI)

Internal Proprietary ToolingImageBounding BoxPolygon
Worked on a large-scale OCR annotation project focused on training and validating Document AI models. Tasks included drawing precise bounding boxes and polygons around words, grouping words into lines and paragraphs based on visual layout and semantic structure, and transcribing multilingual and handwritten text. The project involved reviewing and correcting AI-preannotated outputs, distinguishing scene text versus overlaid text, and ensuring full compliance with detailed annotation guidelines. All submissions were subject to 100% Quality Assurance review, strict accuracy requirements, and productivity benchmarks (AHT).
