OCR react mobile application

Hey guys! I m getting into OCR and my goal is to create an OCR mobile app.
I m still very new to the concepts and have zero experience working with optical character recognition, so I m looking for advice on where to start my work? and what technologies to use?
I want to create a react app and want to use Tesseract engine with open CV do you have any thoughts on how to proceed and what I should learn first?
