Image annotation web app using ReactJS and Ruby on Rails or Firebase

I like to create a free online image annotation app so people can use it to create stickers, memes, etc with images. The app I really admire a lot is [login to view URL] in terms of the way the annotation tools work. Their app is built using ReactJS and I am not trying to create a duplicate. But if you can make the drawing tools (geometrics, circles) work similar, that would be ideal. I have UI mockups done already. Basic feature are: - ability to annotate an image with geometric shapes like rectangles, circles, arrows, text - change stroke and fill properties - image library to add to canvas - login using Facebook or Google account - ability to save, share, edit and export image as PNG Like most of the code to be built using ReactJS and backend can be PHP or Ruby on Rails. Please send me link of projects you have done. Something that has image editing or annotation would be ideal. Also time frame is 1-2 months for project. Please send me link to some projects you have done or your ReactJS image drawing. Again, most important skill is Javascript. Most of the work should be front-end.
