Project Summary

An IT services company (Synatic) hired Limestone Digital to build a React-based website to assist with labeling PDF pages and images for an OCR system, extending an open-source Microsoft labeling tool and integrating it with the client's API. The vendor delivered a front-end that maintained document page hierarchies, supported file upload/delete, managed fields per document/file, and provided a labeling interface. The client reported strong project management, frequent demos and standups, and high responsiveness from the team.
