Custom modifications to opensource node.js / API project

I have a project that runs [login to view URL] API server to host forms. Opensource: [login to view URL] The forms are build on the API server by admins and then displayed via PHP/JS by just querying the API key and rendering with JS. This all works great, though the opensource version of [login to view URL] doesn't have the required options for the "file uploader" to work. So when we build forms all the functions work perfect, but there's no option for adding image/file uploaders to the forms. Details: [login to view URL] This is where you come in! I need someone to git-pull the [login to view URL] source, setup the API server (easy - instructions are in [login to view URL]) then look at the sourcecode and help add in the missing pieces to get the form component "uploader" to be supported. This is opensource so it shouldn't be a problem to add this function if you have the right skills set. The work I want completed would be as such, you git-clone the [login to view URL] source and run your own API server, then make then create a form, once this is working the custom code required for the uploader to function will be built by yourself and demonstrated, I will then pay for the modified code / changes so that I can apply these modifications to my own server. *** Please make sure you read the github and [login to view URL] documentation / examples before submitting your bid, I will be waiting longer to ensure the right person replies and not just instant responses. *** The person chosen will be based on skills and their response saying that they've read and understand the issue and how they plan to solve it. Please don't rush, as I need to ensure the person who takes the job is sure this can be done first. I will only choose a winner toward the end of the allocated time and based on their understanding of the work. Thanks!
