Frontend part of a pet project (SPA) for portfolio

I'm developing the backend part of my pet project and seeking somebody who could help me with the frontend one. It is going to be a single-page application, mostly working with time series data. The main task is to reflect it properly on the web page. I did some work around it (a draft written in React), but I actually have no time to improve it. I'm better off concentrating on the backend part because it needs a lot of attention. I would like somebody to put in order the code, make the app responsive and improve the part responsible for graph representation. It can be a good project for your portfolio.
