Webapp image capture developer

We are developing an AI powered, browser based, web-app to assist users in determining the condition of their health through smartphone eye scans. We have already built the AI/ML model that the web-app will be connected to. We have a template design for the web-app itself. We need an additional web-app developer who is familiar with the Google Image Capture API https://developers.google.com/web/updates/2016/12/imagecapture as well as other best practice methods for capturing smartphone images.
