I’m an AI Data Annotation Specialist and SEO professional with 5+ years of experience supporting machine learning systems and digital growth initiatives. I deliver high-accuracy AI training datasets and pair that work with data-driven SEO and optimization strategies.

In computer vision roles, I’ve annotated aerial RGB imagery for search-and-rescue models and worked on pixel-accurate labeling using CVAT. I partner with ML engineers to improve model accuracy, reduce false positives, and maintain rigorous dataset validation.

Across NLP and segmentation projects, I’ve handled bounding boxes, polygons, semantic segmentation, object detection and tracking, NER, text classification, and sentiment analysis. I consistently maintain ~99% accuracy on large-scale datasets through structured QA and dataset quality assurance.

Beyond annotation, I execute white-hat SEO work—on-page optimization, keyword research and search intent mapping, and off-page link building and audits. I use tools like Ahrefs and SEMrush to track performance, improve rankings, and optimize content using structured data workflows.
