Build Backend and Frontend for Market Basket Analysis Application

Project Description

We are seeking one to two experts to help us build the backend and frontend to an analytical application. This application performs a market basket analysis, letting people know what products were also bought in the “marketing basket” when another product was bought.  This app enables a user to select data available in a SaaS, get the data from a SaaS, run the data through an R model, and generate a related visualization that is displayed within a browser.  The R script is already written, and we have a working prototype for the visualization using D3.JS, but we desire your help to refine, extend, and complete this app.

As such, the work is as follows for the backend:

1. Take the current R script and review it for sufficiency and adequacy for our purpose, and then extend it to take data input in real-time from the SaaS using their API/IDE.

2. Create a server to host and run the R script when a request to do so comes from the SaaS. This server will need to scale to 100-1000 concurrent users.

3. Pass the results of the R script in JSON (or similar markup) to be used in the frontend for visualization (see below).

Related to the backend work is, of course, the frontend work, which should be a single, well-designed page that has dual functionality:

1. The frontend should have a page that allows for the user to select data from the SaaS. The functionality can be created using the SaaS’ API.

2. The frontend should render one or more visualizations of the JSON that results from the R-script.

To help us, in the backend, you will need to know R and have experience using a JAVA-based API and an understanding of javascript and JSON – and ideally using IDEs. To help us in the frontend, you will need to understand javascript/HTML and D3.JS.   Ideally we would like one person to do all this work, but understand that the skill sets may require two people to work together.

It is important that the front-end, which the user will see, be well-designed and aesthetically pleasing. If you feel like you can get us to the technical functionality we want, but don’t have the design skills, that’s okay!  We still want to talk, and can get a designer to help you.  

We are open to using alternative technologies – but prefer open source and free software. This opportunity, once successful, could yield many other projects from us, so we are looking for one or two people to work with in the long-term beyond this project.  For the right person/people, this will be a lucrative and career-building experience, working with well-known entrepreneurs and thought-leaders in the analytics space.
