Ray developed the Tesseract OCR engine at HPLabs Bristol for 10 years, followed by a 3 year term developing the text and line drawings pipelines for the HP PrecisionScan product in Greeley, Colorado. After spending a further 7 years developing a new architecture for the Omnipage OCR product for Caere/Scansoft/Nuance, Ray is now at Google, working on Tesseract again.
