Amend open source code

I am looking for someone to assist me in repurposing an open source project to meet the needs of another project. The original open source project can be found at [login to view URL] I will supply my own Git Repo Papergrapher is a vector editor based on [login to view URL], I require a slimmed down version of this project with minor functionality changes. The intended project will allow the user to upload an image, create paths/boxes circles over the image and export this all as an SVG file. Required Skills Javascript, HTML, CSS3 Desired Python (Although you wont be expected to use Python, the project does run on the most simplistic of Flask Apps) Github I require: Limit the upload of images to one.\ Larger Images should shrink to fit the screen -see images That one image is now regarded as the canvas, if the image is moved any subsequent layers will move with it, the canvas will represent the dimensions of the uploaded image, zooming will not effect the dimensions of the exported svg. Hide the Uploaded image layer from layers list. Each Box/Circle/Path created, will be it's own layer. (a new layer is created when each Box/Circle/Path is created) All Box/Circle/Path will have 1 stroke and a 50% opacity fill using #5bd5df When layers are created they are given a the class "Layer" (I will change classname this later) and unique hash for a class - this will be retrieved via Ajax. You may use dummy data as I will set up the backend, if you need me to throw together a quick route I can. Example Class, class="layer a5c7df" Layers will also be named in the layer list by unique hash (Currently it uses "Layer of SOMETHING") When saving, rather than spitting out JSON, the JSON with be saved via AJAX POST to a database. Again I'll go the backend I just require the front end Expected shortcuts should also function i.e. Cmd Z on mac should Undo Please let me know if you have any questions, I may require revisions.
